The invention relates to energy, in particular to a device for receiving heat generated otherwise than by combustion. It can be used for thermal energy production and organization of heat supply in areas where there are the necessary conditions for the inventive downhole heating system with underground teplogidravlicheskie, then CST FRI-G-A, including for decentralized heating Autonomous, remote from centralized utilities consumers. CST FRI-MR. AND insures produced by using the heat energy in hot water without the supply of this energy from outside. It can work using low-temperature surface water or groundwater, usually located in the upper intervals of the earth's interior, or by their combination.

In addition, the claimed CST FRI-G-a can be used to create reserves of heat and underground accumulation of heat in the warmer months, mainly during the summer periods of floods and store it for later use in the cold season (heating period) on heating, ventilation and hot water, meaning it can be used for energy supply and first remote areas. Use the s it will reduce the cost of implementation of the "Northern territories". Its application will also allow you to be free from defect, characteristic of deploystudio with fuel burn, lower emissions (from combustion) and to improve environmental conditions at the location of the heat source. Declare CST FRI-G-AND can expand the range of non-traditional renewable energy sources (RES).

It is known that the release of heat into centralized municipal heat supply in Russia is 1/3 of the total heat consumption (A.P. Baskakov, Berg BV, Witt O.K. and other heating equipment. Textbook for high schools. Edited Apeshkov. - 2nd ed., Rev. - M.: Energoatomizdat, 1991, str, [1]), i.e. district heating systems are common. Such a system (ibid, [1], str-198) includes a source of heat; sometimes the heat accumulator; teplopotreblenija with the relevant trunk, quarterly and individual networks, which teplopoteryami connected with a source of heat. Sometimes the centralized heat supply system may include a stand-alone (local) peak heat sources.

A disadvantage of the known heating system is that the source of heat is the source for providing heat energy fuel combustion, most of this boiler houses and CHP. This disadvantage is due to exhaustion and d is rogovskoy, used fuel, environmental degradation as a result of its combustion. Another disadvantage of the conventional heating system is its high cost associated with the costs for the creation and operation of heating systems, poor condition which additionally leads to thermal losses, the total share in heat supply systems is 23.5% (Bashmakov I.A. "coaster" inefficiency. The magazine "news of heat supply", M, 2006, No. 12, p.14, [2]).

The development of fuel-energy complex of Russia and the world anticipates the need for reduction of consumption of fossil fuels (oil, oil products, gas, coal) as boiler and furnace fuel. At the same time, it is envisaged to increase the scale of use in the national economy of renewable energy sources, including hydraulic and geothermal.

Obviously the advantage of the use for the purposes of heat deep heat of the Earth (Hajiyev A.G. and others Geothermal heat. M.: Energoatomizdat, 1984, [3]). This build teplovodosnabzheniya well, equip it, organize the extraction of heat energy in hot water (rarely paired), convey heat to the consumer, use it for heating, utilizing "spent" fluid and relieve. D is I use heat geothermal wells proposed interesting solutions, for example, (alhasov A.B. RF Patent for the invention №2105351 C1. The method of dual use two cernovodeanu layers. Bull. No. 5, 1998, [4]). Technical solution allows you to organize geothermal heat using two deep gorjachevodsk zones.

The difficulties involved in fuel-economic balance of the country deep heat of the Earth with the use of these analogues are a number of reasons, including the following: the uneven distribution of geothermal, affordable hot groundwater throughout the country, for example, their share in Eastern Siberia and the Far East is only 17% (Hajiyev A.G. and others Geothermal heat. M.: Energoatomizdat, 1984, [3]); high costs, including exploration, construction, arrangement, organization, control and cleaning of works on the organization of production, use, recycling and disposal. On the high costs of the impact and what are thermal water at a great depth, as a rule, deeper than 2000 m

It is known that the resources of geothermal energy are divided into hydrological and petrogenetically (Gnatus N.A. Thermal energy of the Earth is the basis of the future power system. The magazine "news of heat supply", M, 2006, No. 12, page 27, [5]). The first of these is represented by a coolant - groundwater is, steam, steam-water mixtures and constitute only 1% of the total geothermal energy resources. The latter represent the geothermal energy contained in the hot rocks.

Fountain technology (the well-springs of underground heat sources) are rare not only because of its scarcity, but also expensive due to the depth of occurrence of geothermal waters, and also because of the need for additional processes associated with ensuring its circulation (with clearing) in the heating system.

For promising energy the use of geothermal energy enclosed in a hard, hot rocks and constituting 99% of the total resources of underground thermal energy (Gnatus N.A. Thermal energy of the Earth - the basis of the future power system. The magazine "news of heat supply", M, 2006, No. 12, p.29-30, [5]).

The well-known scheme of geothermal circulation system with artificial reservoir, a series of vertical, formed by hydraulic fracturing (Gnatus N.A. Thermal energy of the Earth - the basis of the future power system. The magazine "news of heat supply", M, 2006, No. 12, p.30, [5]), including injection wells, production wells, fractured as a result of high temperature fracturing rock mass geo - thermal collector installed on the surface teplopotreblenija device: the circus is arianny pump, the intermediate heat exchanger, heat exchangers consumer. Teplopotreblenija device connected to the injection and production wells. As world experience shows (Gnatus N.A. Thermal energy of the Earth - the basis of the future power system. The magazine "news of heat supply", M, 2006, No. 12, p.31, [5]) it is effective: the production of fluids in such installations 2-5 times more profitable obtained in thermal and nuclear power plants; the ROI is 4-5 years; it can be operated for a period of not less than 25 years.

However, the payback period (as an indicator of the economic efficiency of the installation is provided at a certain (not below the threshold level) the consumption of the produced heat. The high cost of installation are required while drilling the borehole with the drilling depth of 4-6 km of Their value in fixed assets installation is 70-90% (Gnatus N.A. Thermal energy of the Earth - the basis of the future power system. The magazine "news of heat supply", M, 2006, No. 12, p.30, 32, [5]). Therefore, referring to the remote, isolated, often with a small consumption settlements, to ensure the economic attractiveness of interest and other technical solutions installations of similar purpose, but with significantly less depth technological Teploenergo is their wells (and less expensive).

Known borehole heat source (Decision dated 06.12.2007 G.O. grant of the patent for the invention "Borehole heat source" on the application number 2006132584/03(035452)filed 11.09.2006, M CL F24D 3/08, [6]), containing teplovodosnabzheniya well connected to the water source area of runoff and teplovozostroitel, teplovodenergiya well is drilled so that her face is intersected by the tunnel, while teplovodenergiya well serves as a conduit for the water source adopted surface water, which drilled teplovodenergiya well or aquifer area or zone, or surface water with groundwater zone or zones, and for the area of flow made the crossing teplovodenergiya wells with lower adit, coupled with well vortex generator mounted under its dynamic level. The water pressure is sufficient to generate thermal energy, and teplovozostroitel through teplovodopribor connected in the area of the flow teplovodenergiya well to the exit of the vortex generator. Vortex generator is located in the tunnel and connected to the well in its intersection with the tunnel, equipped with a pumping unit from the piping. Teplovodopribor is an additional well drilled from the tunnel before crossing it with the surface or underground talocrural the torus, to which drilled from the surface and mastered well hot water.

For the implementation of the heat source is not required drilling deep (4-6 km depth) of the well. The depth of the well may be, as a rule, 300-1000 m In the borehole is installed vortex generator under dynamic water level (from surface or underground source)necessary for the operation of a vortex generator. Heated after vortex heat generator water is directed through the borehole in an underground deploydirector located generally at a depth in the range of 300-1000 m Costs for the construction of such underground geothermal heat storage source of heat is much lower compared with the geothermal circulation system with artificial reservoir (discussed above), providing drilling and formation of the reservoir at a depth of 4-6 km

A disadvantage of the known borehole heat source is that the vortex generator is installed in a specially built mine workings-the adit, which has an intersection with the rig (hydropower) well. The construction of additional excavation for the implementation of downhole heat source complicates its design, increases the cost of its implementation.

Famous talouden Bauma well (Elisha A.D. RF patent for the invention №2291255 C2. Teplovodenergiya well. M CL EV 3/00; F24H 4/02. Publ. 10.01.2007,, bull. No. 1, 2007, [7]), using low-temperature surface water or groundwater, located in the upper intervals of the earth's interior, or by their combination, and is affordable for the production of hot water and steam, and adopted as a prototype. It contains the source water area runoff and teplovozostroitel. In mountainous terrain with slope teplovodenergiya well drilled directed or inclined and thus that her face traversed the hillside and it is associated with the surface, while teplovodenergiya well serves as a conduit for the water source adopted surface water, which drilled the well or aquifer area or zone, or surface water with groundwater zone or zones, and the zone of flow made the intersection of the well with the slope of the mountain the surface or the intersection of the well with lower adit, with well established vortex generator disk type under her dynamic level, water pressure sufficient to generate thermal energy, and teplovodopribor connected in the zone drain well through her harness.

The lack teplovodenergiya well adopted for the prototype, zakluchat is limited only mountain, and downstream tunnels the conditions of its application. It is not possible to develop and use the heat in other common conditions, including the conditions of the plains. In addition, it is not possible to accumulate and long-term storage of heat, for example, when its summer production, particularly during flood periods, and winter consumption during the heating season. To the disadvantage of the traditional scheme of teplopotreblajus (geographically dispersed area) should be attributed to the high cost of its thermal networks. They (heat networks) can be tens and hundreds of kilometres of pipelines are often laid underground. Capital costs for construction and periodic replacement of heat pipelines represent a significant value. In addition, the location of thermal networks on the surface in conditions of sharply continental climate often leads to accidents in the winter, their peripersonal, the consequences of which are additional repair costs and the emergence of social tensions caused by the violations or lack of heating. To the disadvantage of the traditional placement of heating systems should include the fact that extensive heat networks with attached teplopoteryami represent a system difficult to implement them to regulate the to, and they heat distribution networks (due to the often poor condition) to cause significant heat losses.

The task of the claimed downhole heating system with underground teplogidravlicheskie, then CST FRI-G-A, is an extension of the conditions of its application (heat energy in mountain and plain areas), expanding its functionality - making it possible to accumulate and store, as defined by thermal energy, as well as the implementation of a closed cycle heat with minimizing the cost of building thermal networks teplopotreblajus and thermal losses in them.

To achieve the technical result in the accepted prototype containing a source of water connected with a nutrient tank which is connected with the conduit, the lower end of which is connected to the area of the drain that is installed in the conduit, the turbine is kinematically connected with the downstream vortex generator disk type, a block which is executed with a possibility of fixing and their perception of the reactive moment of the supporting member below the dynamic water level, the pressure which is sufficient to generate thermal energy, the conduit is a well, the source of water is surface water, which well was drilled or re is urenna her and communicated with her underground aquifer area or zone or surface water with groundwater zone or zones of the message nutritional capacity of the pipeline is equipped with a device controlling the flow of water, such as regulators, valves, interval of the well to the place of installation of the vortex heat generator drilled vertical, teplovozostroitel with heat networks having input and output pipelines, in the inventive downhole heating system with underground teplogidravlicheskie turbine and vortex generator is coupled to a disk-type and are well hydrocephalia, housing rigidly connected, the turbine is located above the vortex heat generator of the disc type, a support element is a column of pipe is lowered into the well, the upper end of which is secured to the wellhead, hydrocephalia connected with the lower by the end of the tubing, the area of flow is absorbing interval of natural or synthetic origin, such as*(*Arrays of natural occurrence of rocks known various technologies create collectors - zone flow (Ahrens WE Borehole mining. M., Nedra, p.16-17; 266; 269, [10]): hydraulic fracturing; the explosive destruction; the drilling system of horizontal wells; education tanks underground dissolution, underground leaching, the earth smelting and others), formed by the fracturing fracturing manifold, it further includes a production well, which peleburan formed by fracturing hydraulic fracturing manifold communicated with her, and in conditions when the downstream absorbing interval does not intersect with the vertical track well spacing well below the installation place is hydrotalcite drilled directed to the intersection with the zone of flow, the inlet pipe of teplovozostroitel connected to the production well, and its output pipe to the well.

In downhole heating system with underground teplogidravlicheskie as a hydraulic machine can be used turbodrill.

In downhole heating system with underground teplogidravlicheskie may be several wells and production wells.

In teplovodenergiya well production well may be either water or vodostochnoi.

The set of features of the proposed CST FRI-MR. AND allows to achieve the technical result, in particular:

first, to expand the conditions for its application by providing heat energy not only in the mountain areas, but also in terms of flat terrain. This is achieved by the fact that a well installed in her vortex generator perebor is in the area of Stoke - the collector, in which accumulation of produced heat energy in hot water. Thus is formed an underground stagnant volume of hot water. Collector with hot water, pelaburan and production well through which hot water can be transported to teplovozostroitel on the surface. This scheme generation and transportation of heat working in mountainous terrain, and in the plain;

secondly, to extend its functionality by providing the ability to accumulate and store the generated thermal energy.

Thus formed underground volume of hot water is hydrodefluorination. Research and practical experience shows (Kabus F., Bartels Y. Underground accumulation of heat and cold. The magazine "Teploenergetika, No. 6, 2004, p.70-76., [8])that such underground hydroseparator is effective and economical. For example, hydrodermabrasion allows you to store heat produced in the summer, during the time before the heating period, and also during the period (ibid., [8]), which is 8-9 months. Thus, underground fractured reservoir is both a storage tank and storage of thermal energy in the water;

thirdly, use as hydraulic machines squaring the turbodrill (Gresov I.S. and other Turbine drilling deep wells. M., Nedra, 1967, [11]) allows to reduce the costs of development work to create it, because it can be used commercially-manufactured turbo-drill designed for use in downhole conditions. The specifics of these conditions are: the limited diameter defined by the diameter of the hole; work under high hydrostatic pressure; flowing contaminated water, which may contain abrasive particles; high temperature downhole conditions and other). An operational advantage of the turbodrill is that the elements of its attachment to the drill string of pipe is uniform, and it is adapted to operate in downhole conditions;

fourth, the use as a support element of the column of pipes fixed in the borehole at its mouth (by analogy with turbine drilling) allows to provide the perception of it (casing pipes) reactive moments turbodrill and vortex heat generator and to ensure the efficiency of the proposed scheme;

fifthly, the connection of the input pipeline of teplovozostroitel with production well, and its output pipeline with well helps to ensure continuity (closed circuit) operation of the heating system and to improve its environmental friendliness, with a simultaneous increase is the group of energy efficiency and achieve water conservation (resource).

After teplovozostroitel water temperature is relatively high, and its release could lead to thermal pollution (Hajiyev A.G. and others Geothermal heat. M.: Energoatomizdat, 1984, [3]). In the inventive CST FRI-MR. AND this disadvantage is absent, and in addition, it increases its energy efficiency. Energy efficiency is a higher temperature coming from teplovodomernaja coolant due to more complete extraction at each cycle "production - consumption" circulation) ceteris paribus. Water conservation effect is that it is the circulation (little changed) volume of water which is cyclically subjected to heating - cooling (generation - consumption of heat) by analogy with other types of heating systems.

In addition, underground storage tank, storage of hot water (collector) has a certain size, the projection of which on the surface can "get" and rivers, and mountainous terrain, ravines, swamps, which complicate the gasket in position of the surface thermal networks of dispersed teplovozostroitel. Therefore, in justified cases, the appropriate message is dispersed on the surface of teplopotreblenija with an underground reservoir through wells and production wells (and not the surface of the governmental networks).

(For more, including backup) wells and production wells can improve its system reliability due to the possibility of "transition" on them in case of accidents on surface heat networks.

In addition, also in the case when the mouth of the production well is located above the underground reservoir filled with hot water production well is a water and shall be equipped with a water-lifting device. When the mouth of the production well is located below the position of underground hot-water collector (mining), mining well is freely flow and requires no equipment of its water (pump) installation.

It should be noted that the produced and implemented using the inventive CST FRI-MR. AND hot water cost close to geothermal energy, which in 5-30 times lower than the cost of energy produced by the boiler-houses on traditional fuels (Batishchev V.E., Martynenko astray freight, Detectives S.L., Liquor EM Energy efficiency. Reference manual, Ekaterinburg, RIA "Energo-PRESS, the EPA under the gun-UPI, 1999, p.38-39, [9]), but is predicted even less due to lower costs of less deep well.

Works claimed CST FRI-G-A in the following way.

CST FRI-G-a in figure 1

Well 4 is in communication with the source of water 1 representing the stream of natural origin (it can be communicated to and from an underground water source aquifer area). Mouth part of a well-lined casing pipes, perforated part 7 which is designed to regulate the flow of water from the water source 1 into the borehole. Outside of the perforated part of the casing 7 is installed with the ability to turn on her perforated pipe 8 so that is Erste its perforation 8.1 may coincide with the holes of the perforation of the casing 7, and the other angle of rotation of the nozzle 8 does not match. These two provisions of the socket matches either "open" or "closed" position for movement of fluid from the source 1 into the well.

Well, at its mouth by means of a rigid connection 9 with the casing pipe 7 is installed column pipe 6 with a coupling 6.1 at the lower end. The clutch 6.1 through clutch 2.6 connect the turbine 2, which used the mud motor, which via a rigid connection to their dwellings attached vortex generator disc type 3. The gap between the housing hydrotalcite and the borehole wall covered with a special sealant 2.1. Turbine 2 and vortex generator 3 is coupled. Column pipe 6, is rigidly secured to the wellhead, is the supporting member and perceives the reactive torque arising during operation of the turbine and vortex heat generator disk type.

In the coupling 6.1 holes, which are messages annulus of the well volume with the inlet of the hydraulic channel of the turbine. During the Assembly of the tubing 6, the turbine 2, the vortex generator is of the disc type 3 and the open position of the nozzle 8, as a regulating device, water from source 1 through the perforation holes 8.1, the holes in the casing pipe 7, the number of the core channel wells moves down, in the absorption zone 5. While it is moving through the holes in the coupling 6.1 and fed to the inlet of the turbine 2.2, the output of which is fed to the input of a vortex generator 3.1, the output channels of which 3.2 directed towards the absorption zone 5.

Well, pelaburan absorbing interval 5 (dummy area). In this example, the absorbing area is the area represented by filtration rocks, in particular aquifer (not moving it with water) zone with the ability to replace water in it*(* Array of natural occurrence of rocks known various technologies create collectors - zone flow (Ahrens WE Borehole mining. M., Nedra, p.16-17; 266; 269, [10]): hydraulic fracturing; the explosive destruction; the drilling system of horizontal wells; education tanks underground dissolution, underground leaching, underground smelting and others)

The hole in the bottom part lined perforated pipe 4.1.1. Through the holes in her hot water enters the absorbing interval 5, filling it. In the inventive CST FRI-MR. AND drilled and mastered production well 10. For lifting hot water it is equipped with a lift pipes 11. In the lower part of the water column of pipes installed perforated pipe section 10.1 and a submersible pump with electrodirt the LEM 12, connects power from the supply line 18. To the cap 13 production wells through the valve 14 attached teplopoteryami 16. After consumer use heat hot water last cleared the water purification device 17 and is directed to the entrance slit (in the working scheme of heat supply).

The static level in the well is Harticle=31 Ohms. The dynamic level when the well water source is located at the wellhead and is

Harticle=Om. Thus, the dynamic pressure (total)acting on the turbine and vortex generator (consumed) disk type, is 310 meters

The water flow through the wellhead regulating device coming from the water source 1 well is 1000 l/min Depth position of the roof permeable underground thermal storage zone is L=430 m Highest power in this zone is 36 PM

The maximum hydraulic capacity of Ngdeveloped hydropower flow in the borehole CST FRI-MR. AND under dynamic pressure equal to Nn=310 m, and the water flow rate is equal to Q=1 m3rpm is around Ng=50 kW, and the heat generated is 71000 kcal/hour. Electric power submersible pump production well is NEN=50 kW, and its about socialnet Q n=0.7 m3/min

CST FRI-MR. AND figure 2

Mainly the design of individual devices and components CST FRI-MR. AND shown in figure 2, the characteristics of the used equipment, operational parameters, the linear dimensions similar to those shown in figure 1. The only difference is that the absorbing interval 5 figure 2 does not intersect the trajectory of the vertical bore 4. To ensure crossing interval of the well 4.2 below the installation place is hydrotalcite drilled directional, that is, the area of the borehole 4.2 is curved.

CST FRI-G-AND can operate in two modes: harvesting thermal storage and heat supply.

Work in harvesting thermal storage mode

Wells 1 and 2 in this mode are as follows.

Production well 10 is disabled (idle) condition from the control station 19 disabled submersible pump motor 12. Teplopoteryami 16 off valve 14 from the water pipe 11. Water from the water purification device 17 is not received in the hole (or in the nutrient capacity of 1).

Procurement and teplokomunenergo hot water in the absorbing zone 5 is provided, usually in the summer in the flood period. The water from the feed tank 1 in the open position of the holes in the pipe 8 enters with vagina 4, filling it and leading in a dynamic condition in which the dynamic level in the well rises. In the dynamic condition of the water below the dynamic level moves to the absorption zone, filling it with hot water. As you fill the hole the dynamic level is around, coinciding with the mouth of the well. In this position the head on the turbine 2 and the vortex generator is Hn=310 m, and hydrocephalia develops power 50 kW with output vortex heat generator 3.2 well in absorbing 5 zone hot running water with a temperature of 95°C and accumulating, because the absorption zone is stagnant. Instrumentation installed in the borehole and at its mouth (not shown), is monitoring and recording of parameters to be heated and injected into the absorption area of water, in particular its temperature, flow rate and volume, pressure. These parameters are monitored and recorded using sensors similar to the parameters established in the mining well. During the harvesting of hot water filling the absorbing zone is carried out in a reasonable amount, including the amount of heating system, which will operate during the heating season. For the considered CST FRI-MR. AND this amount stood at the focus of 20000 m 3. After the specified volume of hot water is pumped into the absorption zone, the process of working CST FRI-MR. AND harvesting thermal storage mode finish. For this purpose, the nozzle 8 is switched to the "closed"position, in which it is located before the heating period. The state converted to hot water and pumped to teplokomunenergo and its storage in the aquifer zone of the coolant in the hot water is controlled by the readings of measuring instruments: temperature, volume, level, etc.

Operation mode heating

In this mode, connect to the work of the production well 10 by connecting it to the control station 19 to the supply line 18 submersible pump 12. Open the valve 14 and the hot water in the water pipe 11 from the absorbing zone 5 is supplied to teplopotreblajus 16. The "who" heat hot water from teplopotreblajus 16 enters the water purification device 17, and from there into the well on the next cycle of its movement through the heating system. Thus from the feed tank into the circulation system to the input well through the regulating device (socket 8) is added the desired amount of water to provide circulating in the system volume.

Declare CST FRI-MR. AND allows you to:

- procure, implement underground teplokomunenergo and storage t is plooy energy;

- to carry out the heat, performing the function of a heat source, underground teplokomunenergo and store thermal energy;

to improve the reliability of heat supply, including due to the redundancy of traditional heating systems or their parts.

Work claimed CST FRI-MR. AND most effective in the areas of decentralized energy supply, where necessary for its operation conditions.

Its use will help to reduce the cost of implementation of the "Northern territories" of fossil fuels.

Due to the fact that the claimed CST FRI-MR. AND based on environmentally friendly technologies for the production of thermal energy, and its appearance does not generate impressions industrial facility with traditional chimneys, it can be successfully used in areas of recreation and leisure facilities and treatments, landscape, tourism, and national parks and nature reserves.

In addition, placement of the heat source, wells and production wells claimed CST FRI-MR. AND in the earth "makes it more secretive and invulnerable.

Regarding stealth. Currently, the detection of the facilities easily accomplished using infrared, including optical systems. The heat source of the proposed CST FRI-MR. AND such systems cannot be found, Wien, because of its thermal radiation is shielded by the layer of earth above teplovidelyaushy areas, wells and production wells.

Relative invulnerability. Located above the heat source CST FRI-MR. AND earth's mass is large, loud and power (depth) located on top of the rocks, and shells on the ground (while trying her vulnerability) does not affect its healthy state. This explains the high survivability of the proposed CST FRI-G-a, as well AS the possibility of dual use of it in civilian technology and military purposes, including in times of war.
