The invention relates to energy, in particular to a device for generating electricity without burning this fuel. It can be used for production of electric energy and organisation of electricity supply in areas where there are the necessary conditions for work claimed borehole pumped storage power plant (hereinafter - shoes), including the decentralized Autonomous power supply, remote from centralized utilities consumers. Use it most effectively in conditions of uneven - primary energy consumption in the summer period (when shoes works in the turbine mode) and the lack of electricity consumption in the winter period (shaes is running in pump mode). Shoes insures produced with its use of electrical energy without the supply of energy for that outside. It can work using surface water or groundwater, located in the upper intervals of the earth's interior, or when they are combined. The claimed shoes allows to expand the range of non-traditional renewable energy sources (RES).

Known downhole hydroelectric power plant (Generation of electricity during the injection of a denste fluid into a subterranean formation. Patent US 4132269 And CL. EV 43/20, F03G 7/04, publ. 02.01.1979 year). Well the guide is elektrostantsia includes a source of water, coupled with a nutrient tank which is connected with the conduit, the lower end of which is connected with the zone of flow below the point of the message of the conduit with a nutrient capacity installed in the lower part of the conduit of the hydraulic machine such as a turbine, kinematically connected to the generator, the conduit is formed of mining production, such as drilling a well, drilled to a zone of discharge for the water source adopted surface water, which drilled the well or aquifer area or zone, or surface water with groundwater zone or zones, the water is supplied by a device controlling the flow of water, such as regulators, valves, and the generator reported by cable, installed in a borehole from the surface at the wellhead.

In the invention fixed characteristic of hydroelectric power from dams scheme disadvantages. They is that the required water pressure is achieved without the cost of building dams and the associated negative consequences of economic, social, ecological and climatic character. In addition, the invention allows to extend the terms of its application is trouble - free operation under conditions of sharply continental climate, frost and flood periods, as well as work not only with the use of surface water sources, but underground or in combination. These effects are essential and the financial equivalent.

Hydraulic power flow downhole hydroelectric power is generated in a borehole drilled to the absorbing interval, the result is generated when this flow of water from an upstream source in the absorbing interval. The height of the flow in the well and, as a consequence, its pressure may be greater value from meters to kilometers, and the pressure from tenths of MPa to several tens of MPa. Without the construction of a dam known technical solution (prototype) allows to obtain a high value of power flow in the wells hydroelectric power plants under the same water consumption (in comparison with low-pressure, dams) - high hydraulic and produced electrical power (without the construction of a dam).

Sources of water flow in a borehole can be connected to either surface (river, lake, sea, swamp, reservoir, products of melting glaciers, drives technical water and others), or perebrannye bore and connected underground aquifer, or a combination thereof. The establishment of a work flow of water borehole hydroelectric power in the earth, with positive year-round temperature, allows to exploit skvazhina the hydroelectric power plant to generate electrical energy year-round in conditions of sharply continental climate.

Known downhole hydroelectric power plant can indefinitely operate when the area of flow is crossing the permeable interval with the earth's surface is mountainous terrain, situated above the river flow, or it is receiving an infinitely large volume of water, when the absorbing zone is a powerful permeable interval, usually represented by sandstones, Sands or karst and cavernous rocks in carbonate rocks. Such powerful absorbing intervals can travel considerable distances (up to tens and hundreds of kilometers) and is able to accept large volumes of water (Gordeev PV, Semolina VA, Shulakova O.K. Hydrogeology. M., "Higher school", 1999, str-332), in practice they are often used for waste disposal for decades, and when used as zone drain well hydropower can provide an infinitely long period of its operation. A disadvantage of the known borehole hydroelectric power is that the conditions for its application is limited.

The reason is that the area of flow can be represented by an underground capacity limited amount of filling which is subsequently filled the hole up to her mouth, and hydrodynamic pressure of the water in the well acting on the turbine, prinimaetsia value (because the conditions for the movement of water in the well is not available). Such conditions rarely exist in mountainous terrain and often in plain terms. It is known the existence of underground reservoirs of natural origin, and Geotechnology formation of underground tanks (Ahrens WE Borehole mining. M., Nedra, 1986, p.16-17; 266; 269): hydraulic fracturing; the explosive destruction; the drilling system of horizontal wells; education tanks - underground dissolution, underground leaching, underground smelting. Effective is Geotechnology, providing education underground storage tank, for example, by leaching with subsequent collapse of its vaults (Dadykin UD development Problems of thermal energy from hot rocks. Physical processes of mining, VIP, 1982, p.12). Known recommendations for increasing the duration of the period of use of the underground reservoirs (ibid, p.14), providing for the creation of multiple distributed by area collectors with alternate input as they are filled. However, due to limited amounts of filling, conditions of use well known hydropower limited.

Famous pumped storage plant (Baburin B.L., Gluten PPM, Krasilnikov F, Scheinman LB pumped storage plant. Edited Lubkeman. - M.: Energy, 1978), PR is changing as maneuverable regulatory capacity: per diem, the inter annual. Pumped storage power plant includes spaced at different heights of the upper and lower pools, connected by a conduit defined therein a hydraulic unit is reversible hydraulic machines and a latch. The upper pool has no water inflow, and the work station is using the same volume of water pumped from the bottom of the pool at the top (pump mode) and creativesage in turbine mode, in which water flows from the upper basin at the bottom. However, only a small water losses occur through evaporation and infiltration. In the turbine mode produced by the station with electricity for the deficit in the power grid during periods of excess power to the grid its share is used to provide a work station in pumping mode in which the water from the lower basin unit - reversible hydraulic machines is pumped into the upper pool is hidroakumuliacine needed to further support the operation of the station in the turbine mode (next loop power control). The principle of operation is known, the pumped storage plant is interesting and can be used to extend the operating conditions borehole pumped storage plant, but its technical " is not obvious.

For the prototype of the proposed borehole hydroelectric adopted downhole hydroelectric power plant for U.S. patent (Generation of electricity during the injection of a denste fluid into a subterranean formation. Patent US 4132269 And CL. EV 43/20, F03G 7/04, publ. 02.01.1979 year). It contains a water source which is connected with him conduit, the lower end of which is connected with the zone of flow below the point of the message of the conduit with a nutrient capacity installed in the lower part of the conduit hydraulic machines, kinematically connected with electromachine, electric communication line electrical machinery with electrocommunications Converter shield on the surface at the mouth of the well, the conduit formed by drilling the well, drilled to a zone of discharge for the water source adopted surface water, which drilled the well or aquifer area or zone, or surface water with groundwater zone or zones.

The disadvantage of it is that it is not well pumped storage power plant, and its use is limited. It cannot be used for reliable electricity generation in a limited amount of underground reservoir, which is the area of the water flow.

The technical result, which is aimed invention is to create a borehole pumped storage plant with Bo is its wide application in conditions of the limited amount of underground collector, in comparison with the prototype, and which (for the consumer with the load only during the summer period and located in areas with favorable wind resources in winter) complex Autonomous non-traditional renewable source of electrical energy.

Achieved the technical result of the claimed borehole pumped storage plant that adopted for the prototype downhole hydropower plant, including the water source which is connected with him conduit, the lower end of which is connected with the zone of flow below the point of the message of the conduit with a nutrient capacity installed in the lower part of the conduit hydraulic machines, kinematically connected with electromachine, electric communication line electrical machinery with electrocommunications Converter shield on the surface at the mouth of the well, the conduit formed by drilling the well, drilled to a zone of discharge for the water source adopted surface water, which drilled the well or aquifer area or zone, or surface water with groundwater zone or zones in which the hydraulic machines and electromachine and are coupled to the downhole unit, made with the ability to work in turbine mode, it electromachine made in the form of an electric generator, and hydromachine - in the form of a hydraulic turbine or pump mode, it electromachine made in the form of an electric motor and hydraulic machines - in the form of a centrifugal pump, downhole hydraulic unit is equipped with a latch, and the area of flow is communicated with her absorbing interval of natural or artificial origin downhole unit is installed under the dynamic level, creating a pressure sufficient to generate electricity, the power source is made with the possibility of its connection for lifting water from absorbing interval and feeding into the source water or the electromachine downhole hydraulic unit operating in pumping mode; or to the motor of a submersible pump connected with the lower end water column of pipes installed in a production well, which peleburan absorbing interval and communicated with her; or to the motor of the compressor pneumatic water lift, containing a source of compressed air - compressor, injection well drilled to the absorbing interval and will be with him, and with a compressed air source, water well drilled to the absorbing interval and a built-in lower part with him, and in its upper part of the chamber connected with a source of water, with a water well is in communication with the absorbing interval n the same messages with him the injection well; while drilling, the water and production well connected with a source of water, with the intersection of the borehole with an absorbing interval equipped with remotely operated shutoff device and the power source is wind energy installation.

In borehole pumped storage plant of the drill hole can be peravurani several completely unconnected absorbing intervals, and the downhole unit (hydraulic power) made with the possibility of its installation at the roof of any of absorbing intervals or each of them at the same time.

In the water, moving and circulating in the borehole pumped storage plant, there may be an additive that reduces water flow rates, such as sulfonic acid.

Source of water in the borehole pumped storage plant can be located on the surface of the nutrient reservoir with water.

The features of the proposed borehole pumped storage plant allow to obtain the desired result. In particular, the supply of different (alternative) lifts water from absorbing interval, the electromotive actuator which is connected to a wind energy facility allows you to reuse a limited underground absorbing gap and to extend the terms of use of shoes. In addition, for consumers with load occurring only in the summer, and located in areas with favorable wind resources in the winter, when the underground volume of the absorbing interval, sufficient to operate the station (and covering the required electrical load) throughout the summer period, the characteristics of the claimed shoes allow you to make complex non-conventional source of renewable and implement a reliable energy supply for long time, including annual, intervals.

Perebrannye well some completely unconnected absorbing intervals and performing downhole unit (hydraulic units) can be installed at the roof of any of absorbing intervals or each of them at the same time allow you to extend the conditions for its application by increasing the volume of the absorbing interval.

Additives to the water, for example, sulfonic acid, moving (circulating) elements borehole pumped storage plant (drilling, pumping, mining wells, absorbing interval and others), reduce flow rates (mirzadjanzade AH, Karaev A.K., sirinzada Hydraulics S.A. in drilling and cementing oil and gas wells. M., Nedra, 1977, p.86) 18-20% and the energy costs of overcoming them, and those who - to increase energy efficiency and achieve energy saving. In addition, additives are surface-active substances (surfactants), such as sulfonic acid, allow to exclude the formation of sediment hardness salts on the surfaces of micro-cracks and pores of permeable rock through which water moves through permeable underground interval. In the presence of surfactants do not form dense postponed on the surface of the flow channels water deposits. Related to this is the save (no deterioration) of the conditions of a water permeable interval of time.

The device shoes

Electricity generation of shoes is done with its work in the turbine mode of the unit, installed in a borehole. Its implementation is the only one.

The elements in the turbine mode. Drilled to a zone drain well 1, the mouth of which is in communication with the source of water 2 natural origin, for example the lake (figure 1), is equipped in a certain way. At the wellhead is installed casing pipe 12, perforated, height (corresponding to the depth of the lake - upper is th part) at the mouth of the bore hole 13. In the casing pipe installed ring 14, the perforated holes 15 in the interval corresponding to the perforation of the casing 12. The ring is made rotatable, and in the closed position the perforations 15 in the ring 14 does not coincide with the holes 13 in the casing pipe 12, and in the "open" position coincide. The interval of the well 8 above the absorbing interval, the position of the hydraulic machines 5 electromachine 6 (downhole unit)has a degree of change of the diameter of the hole. The hydraulic machines 5 made in the form of turbines, and electromachine 6 in the form of a generator. As the generator used the electric drill motor used electroboogie, that the rotation of the anchors can operate in the mode generator. As turbines used the mud motor used in turbine drilling. The mud motor and drill suitable for use in a downhole environment.

Using winches used when drilling with removable wireline, cable (with remote control "capture") in the well is lowered is coupled to the electromachine 6 in the form of a generator with a hydraulic machines 5 in the form of a turbine (amount unit) and fixed in step interval 8 well by means of levers 7 release. Disconnecting from cable is pose the CTV special design "capture", the descent on the rope, and head 10 on the electromachine in the form of a generator. The construction of winches for the implementation of the removable downhole hydraulic unit similar in design to the downhole removable kinoplenka (Kozlovsky E.A. and other Reference engineer on drilling exploration wells: in 2 volumes under the General editorship of Prof. Eaacatalog; volume 1, str-368; volume 2, p.56-85. - M.: Nedra, 1984). The design of this device allows you to connect through the "capture" on the cable head 10 on the unit for lifting it together with hydraulic machines 5 in the form of a hydraulic unit (downhole unit), if necessary. Electric communication line (cable) 9, adapted to operate in downhole conditions by logging winch is lowered into the well simultaneously with the descent of the unit. Coupled with electromachine 6 in the form of a generator, on the surface it is connected to electrocommunications Converter shield 11. It should be noted that the hydraulic unit in the well can be installed on the drill pipe, the upper end of which is mounted on the wellhead according to a known device (application for invention "downhole Unit hydroelectric station", No. 2006128649 from 02.11.2006, F03B 13/06, F03B 13/10.

In the claimed shoes three possible lifting of water from absorbing interval is and nutrient capacity (when this unit is operated in pumping mode or in the terminology of pumped storage power plants - in pump mode): 1) the downhole unit is a reversible hydraulic machines, hydraulic machines made in the form of a centrifugal pump, and electromachine - in the form of an electric motor, and for lifting water uses the same borehole, Fig 1; 2) for lifting water using a special production well, which peleburan absorbing interval and which has a water column of pipes with a submersible pump at its lower end, figure 2, 3) for lifting water using special injection well drilled to the absorbing interval, and a water well, which peleburan absorbing interval, 3.

The rise of water in the first embodiment (Fig 1). In electrocommunications Converter Board 11 is performed by the switching circuit, in which the second cable WG 24 WG 19 connected electromachine 6 unit made in the form of an electric motor. The hydraulic machines 5 made in the form of a centrifugal pump. When applying for the electromachine 6 electric voltage from the wind turbine 19 it is capable of running in electric mode. Her anchor is connected to the rotor of the turbine 5, which works as a centrifugal pump. Reversible hydraulic machines (downhole unit) is located in the well in the water below the static level and squag is in communication with the absorbing interval 16.

The rise of water through the second option (figure 2). Node downhole remotely managed overlying device installed at the intersection of the borehole 1 with an absorbing interval 16, is contained in the closed position (figure 5). Is this operation after release well from the unit with the subsequent application by running in the bore of the drill string is installed on the lower end of the hydraulic trobolowsky. In the overlying solid pipe 77 hydraulic Rublevka extending connects with a pipe 77, figure 4. The subsequent rise of the drill with hydraulic rublevkoy moves up and the pipe 77 to its possible upper position (figure 5) until it stops. This spring retainers 76 are in the groove in the pipe 77 and the latter is fixed in the upper position. However, due to the fact that the tube is solid, is in contact with part of the outer pipe with perforations 74, cover them and this stops the message well with absorbing interval 16. Thus, the interrupted message volume wells with an absorbing interval.

It should be noted that if necessary, absorbing interval can be communicated with the atmosphere through the auxiliary hole.

Mining hole 25 drilled so that its peleburan p is glashouse interval 16. In the hole 25 are lowered water column pipe 26 has mounted on its lower end a perforated pipe piece 27 with a submersible pump. Connected to the motor of a submersible pump in the well using an electric cable connected to the surface with the second cable 24 from the wind turbine. The upper end of the water pipe string 26 through the valve 30 and the water supply line 31 is in communication with the source of water 2.

Wind power plant (WPP) 19 comprises a support, on which the wind wheel 20. The rotation of the wind turbine 20 is transmitted is connected to the wind turbine generator 21, and the generated voltage on the cable to the first turbine 22 is transmitted to electroprecipitation WG 23. Electroprecipitation wind turbine 23 is designed to convert the developed wind turbine electricity to the required quality.

The rise of water through the third variant (figure 3). The site overlying the device is translated to the closed position in a sequence similar to the previous case.

To the absorbing interval 16 drilled injection well 33. It comes with a casing with a perforated section in its lower part and reverse remotely operated valve 43, to which the well summed up the cable. In the upper part of the injection wells installed the mouth GE is matitira head 46. Mouth sealing head 46 is connected through a piping and valve 49 to the compressor 32.

The compressor motor 32 is connected by electric cable of the second turbine 24 to electropneumatically 23 which is connected to the wind turbine.

The rise of water in various ways (figure 6. Depicted in Fig.6 borehole 1, which peravurani absorbing intervals 16, 17, 18, provides water lift: using mining hole 25 of the first absorbing interval 16; using water wells 53 and 54 from the second 17 and third 18-absorbing intervals. Devices for lifting water figure 6 using vododoprinos and water wells similar to that shown above in figure 2 and figure 3.

The work of shaes

Turbine mode. (This mode is uniform for all variants of the water lift shoes 1, 2, 3, 5, 6). Works of shoes as follows. The hydraulic unit through electrocommunications Converter shield 11 is disconnected from the circuit wind turbine. As a rule, shoes runs in either the turbine or water modes, which time does not match.

Perforated ring 14 is installed in the "open"position. While water from a surface water source 2 (natural or artificial origin) enters the well 1, well below the downhole unit it moves the I to the zone of flow 4 directionally drilled borehole (curvature of the borehole may be carried out on the plot well below the place of installation of the downhole unit). Because the downhole unit creates a certain flow rates, the water level in the well increases slightly and at a flow rate flowing into the well water Q1after the transition period is set at a certain value of Nd. In the interval from Hdto zone flow set flow Q1where in any section there of its continuity. The flow of water rotates the rotor of the hydraulic machines 5 (hydraulic machines 5 operates in the mode of the turbine). The rotation of the rotor of the hydraulic machine 5 is transmitted is connected to the anchor electrical machinery 6 (electromachine works as a generator). Lever 7, the latch prevents movement of the United hydraulic-electrical machinery (turbine-generator - downhole unit) down under the action of its weight and water flow, and (thanks to the forces of friction in the borehole) perceives the reactive torque produced by the rotation of the rotor of the turbine and the generator armature under the action of water flow, and transmits it to the borehole wall. The generator is oil-filled and hermetically sealed. Electromachine 6 (generator) produces a voltage that is in electrical communication line 9 from the well is passed on the surface, in particular on electrocomm the operating Converter Board 11. Shoes equipped with a regulator frequency and amplitude of the generated voltage driver voltage required quality. From the shield voltage normalized served on the transformation and release to consumers.

Hydraulic power developed by the turbine is determined from the following expression (Malinin NICHOLAS Theoretical foundations of hydropower. M, Energoatomizdat, 1985):

Nr=PnQ1,

where Nr- hydraulic power developed by the turbine, kW;

Pn- the water pressure is perceived by the turbine, PA;

Q1- the flow of water through the turbine, m3/s

After the downhole flow of water 4 after unit is moved to the flow - absorbing interval in which it is accumulated.

Shoes in turbine mode voltage from electropneumatically WG 23, as a rule, is not served on electrocommunications Converter Board 11 (1; 6) and the electric motor drives a submersible pump in the perforated section of pipe 27 (2; 6) and the compressor 32 (3; 6).

The rise of water in the first embodiment (Fig 1). Mode of rise of water in the first embodiment, the downhole node overlapping device is in the open position (figure 4). Perforated ring 14 is rotated in the closed position, in which water and the water source 2 does not come into the borehole 1. Produced by the wind turbine 19 voltage from electropneumatically wind turbine 23 is fed to the electromachine 6 downhole unit (reversible machine), made in the form of an electric motor. The rotation of the armature of the electrical machinery is transferred to the rotor of the turbine, which is made in the form of a centrifugal pump and working as a pump delivers water from a well on the surface, in the water source 2. As well 1 is in communication with the absorbing interval 16, the water from it is pumped into the source 2. Controlled consumption and the amount of pumped water on the testimony of the flowmeter-counter amounts of water, which in figure 1 is not shown due to the high density of graphical material. After all the projected volume of water from the absorbing interval 16 pumped to the water source 2, the reversible hydraulic machines (electromachine-hydraulic machines 6-5) is disconnected from the power supply circuit of the turbine. After that, shoes ready for the next cycle of its operation in turbine mode.

The rise of water through the second option (figure 2). In the mode of water lift for the second variant (figure 2) overlying the ring 14 is rotated to the closed position in which water from a water source 2 does not come into the borehole 1, and the node downhole overlying the device is in the closed position (figure 5).

Produced by the wind turbine 19 voltage from electraprobe is the user of the turbine 23 is supplied via the cable to the second turbine 24 and the cable to the cable in the hole on the motor of a submersible pump in the perforated section of pipe 27. When the supply voltage submersible pump in the perforated section of pipe 27 last delivers water from downhole production well 25 on the surface and then through the valve 30 through the conduit 31 into the water source 2. Controlled consumption and the amount of pumped water on the testimony of the flowmeter-counter amounts of water, which in figure 2 are not shown due to the high density of graphical material. After all the projected volume of water from the absorbing interval 16 pumped to the water source 2, a submersible pump in the perforated section of pipe 27 is disconnected from the power supply circuit of the turbine. After that, shoes ready for the next cycle of its operation in turbine mode.

The rise of water through the third variant (figure 3). In the mode of water lift in the third variant (figure 3) overlying the perforated ring of holes 14 is rotated to the closed position in which water from a water source 2 does not come into the borehole 1, and the node downhole overlying the device is in the closed position (figure 5).

Produced by the wind turbine 19 voltage from electropneumatically wind turbine 23 is supplied via the cable to the second turbine 24 to the compressor motor 32. Compressed air from the compressor 32 through the valve 49 is fed to the injection well 34 and channel compressed air 37 is supplied through the reverse remotely control the admissions valve 43 and the perforated portion of the injection wells in the absorbing interval 40 in casing injection wells 33 in the absorbing interval 16 (the upper part). As growth pressures it (compressed air) displaces water from absorbing interval in a water hole 52, which is fed into it through the perforations of the perforated part of the water wells 58 and reverse remotely operated valve 65. Then the water rises to the surface to the wellhead, and from him through the valve 61 through the line to the water source (pipeline) 64 - in the water source 2.

After all the projected volume (controlled by the flowmeter-counter number at the wellhead, which is conventionally not shown) of the absorbing interval 16 pumped to the water source 2, overlaps the valve 49 and the compressor motor 32 is disconnected from a network of wind turbines. After that, shoes ready for the next cycle of its operation in turbine mode.

The work of shoes in which peravurani three absorbing interval 16, 17, 18, shown in Fig.6, provides for "refinement" of each of the absorbing intervals, similar to the above modes and options.

The implementation of shoes allows you to achieve this before the invention of the technical result.

It can be used as maneuverable for regulation of electric power in the power system, and in conditions when the load is only available in the summer and the consumer is on-site with favorable vetroenergetika the Kimi resources in winter, the claimed shoes may be non-traditional and renewable source of electrical energy. It can be found in regions with a continental climate, recreational facilities and landscape tourism, popular to visit in the summer, objects seasonal (summer). Moreover, in these areas in the winter time, there is sufficient wind resources. An example of such an object can be protected, protected natural space, adjacent to the lake Baikal.

The work of the claimed shoes most effective in the areas of decentralized energy supply, where necessary for its operation conditions.
