Well head is tightened and excess pressure is increased in underground reservoir by supplying compressed air to the well; during thermal destruction of frozen rocks there used as heat carrier is steam which is supplied with constant flow together with additional water; additional water flow is changed to control the water-air boundary level position, and recirculated water forming during separation of sand from lifted hydraulic fluid is supplied to weigh the deposit.
EFFECT: improving development efficiency of underground reservoir in permafrost sedimentary rocks.
The invention relates to mining and can be used in the construction of underground storage tanks and development of mineral resources by way of a hydraulic borehole mining.
There is a method of in-situ development of permafrost placers, including the drilling of the borehole and the casing, the Assembly in the borehole pulp-raising, vodopada and vozduhopodajushchej column of pipes, the formation of production-capacity by thermal destruction of rocks and their airlifting rise of maintaining a level section of the water-air by the compressed air to the roof production capacity with the removal of excess air through the casing .
The disadvantage of this method is in a fixed position section-level water-air at the casing Shoe, which makes it impossible to form stable code generation capacity by adjusting the position of the partition layer is water.
Closest to the claimed technical solution is how well the development of permafrost of sedimentary rocks, including the drilling of the borehole and the casing, the Assembly in the borehole pulp-raising, vodopada and vozduhopodajushchej pipe string, the creation of underground production-capacity with maintaining a given level section air-water flow regulation water supplied air and the way the water-thermal destruction of the rocks with the flow of the heated water to flow equal to or less than the amount of solid material contained in raising the slurry, and airlifting lifting the formed slurry to the surface with water from a reservoir for weighing thawed rocks in the zone of suction with a flow rate equal to or greater than the volume of water raised slurry .
The disadvantage of this method is the need to change the amount of heat supplied to defrost while maintaining a given level section air-water regulation of the flow of the heated water, which reduces performance thawing and, therefore, increases the time to generate production-capacity. In addition, the performance of airlifting rise is limited to low flooding defined by the position of the boundary between water and air.
Our problem is to increase the efficiency of creating an underground reservoir in permafrost sediments by increasing productivity airlifting recovery and improve performance on the thawing of frozen sand.
In the solution of this problem are provided:
- High performance airlifting rise thawed breed by creating additional pressurization of the compressed air in a sealed borehole while maintaining a given level section air-water in developing-capacity
- High performance thawing of permafrost due to steam with constant computational expense.
More effective introduction of heat in the production-capacity for defrosting, as steam is supplied together with additional water, condenses and warming her that improves the conditions of the mixing and heating of water in the development of capacity.
The most efficient is the process of weighing rocks in the zone of suction due to the supply of all recycled water produced during the separation of sand raised from the slurry. It requires no additional tanks on the surface, is used to change the flow of circulating water.
The essence of the proposed technical solution is that the way to create an underground reservoir in permafrost, including the opening of sandy permafrost formation borehole, installing it process columns, feeding him water, compressed air, coolant, creating production-capacity by thermal destruction of permafrost and airlifting lifting the formed slurry of sand on the surface with water to weight of sediment in the area of the suction of air and additional water in the production-capacity management provisions of section level water-air by controlling the flow of water supplied, according to the proposed methods is the seal cap the well and raise excess the pressure in the underground reservoir by feeding compressed air into the well, during thermal destruction of permafrost as a coolant use steam, which is fed with a constant flow, together with the additional water, to control the position of the section level water-air change flow of additional water, and weighing the sediment serves the circulating water, resulting in the separation of sand raised from the slurry.
The sealing cap of the well and increase the excess pressure in the underground reservoir by feeding compressed air into the well can improve performance airlifting rise without increasing the water level in the well.
The use of steam as a coolant during thermal destruction of frozen rocks, served with a constant flow, together with the additional water, provides consistent high performance thawing sand and uniform thawing of the surface generation-capacity due to better mixing in water with the coolant.
The change in the flow rate of additional water to control the position of the section level air-water in developing capacity allows more efficiently, with minimal cost to use the extra pure water obtained from a natural source, while not reducing the amount of heat input for melting the sand.
The supply of recycled water produced the ri Department of sand raised from the slurry, increases the efficiency of the weighing of the precipitate due to the constant flow of water supplied to the zone of the suction of air, and allows the use of plants for dewatering of sand in the scheme of closed water supply without the use of water tanks.
Thus, the totality of these symptoms provides a solution to the problem of increasing the efficiency of creating an underground reservoir in permafrost sediment by increasing productivity airlifting rise through the creation of additional backwater when the air supply in a sealed well and supply a constant amount of heat for defrosting due to the steam supply with a constant flow.
The drawing shows a variant implementation of the method of creating an underground reservoir in permafrost.
The drawing shows a underground water tank including lined tube well 1 and production-capacity 2. Well 1 mounted pulp-raising pipe 3, an air supply pipe 4, the pipe for supplying recycled water 5 and the pipe coolant b with connections to steam supply 7 and additional water 8. The mouth of the well is sealed by a cap 9 having a nozzle for compressed air 10. In the development-capacity 2 shows the position of the section level air-water 11.
The way to create an underground reservoir, and obnajennogo in Fig. 1, is carried out as follows. Mnogoletnemerzlyh sandy layer exposed by the hole 1, which are technological columns 3, 4, 5, 6 for lifting the slurry, compressed air, cooling water, steam and additional water. Production capacity 2 is created by thermal destruction when the steam flow through the pipe 7 and additional water through the pipe 8 into the pipe 6, which heat the water in the development of capacity. As a result of heat exchange on the surface of the developing-tank 2 below the section level water-air 11, is the thawing of frozen sand with his deposition at the bottom of the output, the vessel 2. The circulating water is supplied through the pipe 5 for weighing deposited sand, which when compressed air through the pipe 4 in the form of slurry is sucked in pulp-raising pipe 3 and rises to the surface. On the surface is selected sand from the slurry with the return of the circulating water in the production-capacity 2 through the pipe 5. When the level of section air-water 11 in the development of container 2 relative to the specified level reduces the consumption of additional water supplied through the pipe 8 into the pipe 6, while the lower section level water-air 11 consumption of additional water increases.
To improve the performance of airlifting rise in the sealed tip 9 wells 1 through the pipe 1 is supplied compressed air with the maintenance of overpressure above the section level air-water 11. This helps to ensure high performance airlifting rise even at a low level position section water-air 11 with respect to the total depth of the well 1.
Steam is supplied through pipe 7 into the pipe b with a constant flow that provides a stable and high performance on the thawing of frozen sand. In the pipe 6 through the pipe 8 serves also additional water delivered from a natural body of water or adjacent underground reservoir, the amount of which is determined by the volume extracted from the output capacity 2 sand. When the joint movement of steam and additional water through the pipe 6 steam condenses and heats the water, which, falling into production-capacity 2, mixed with her water, which ensures a uniform height defrosting the walls of the production-capacity 2.
With the increase of density slurry raised through the pipe 3, it reduces the water content, which leads to the rise of a given section level air-water 11. To restore it reduces the consumption of additional water supplied through the pipe 8. With decreasing density raised slurry, it increases the flow of water, which leads to a lowering of the level section of the water-air. In this case, increasing the consumption of additional water supplied through the pipe 8.
When creating underground reservoira pipe 5 serves all of the circulating water without regulation of its flow, that allows you to more effectively weigh the sediment in the area of the suction of air does not accumulate in ground tanks or to dump contaminated water generated during the separation of the sand from the slurry, which greatly simplifies the process of creating an underground reservoir.
An example of practical realization of the proposed method of creating an underground reservoir in permafrost is the construction of an underground reservoir for disposal of drilling waste on the Bovanenkovo field on the Yamal Peninsula. Sandy permafrost layer of sand with thickness of 20 m lies at a depth of 30 m from the surface of the under layer of shale. The layer of sand open well 1 with a diameter of 400 mm and a depth of 50 m, which grow to a depth of 30 m casing with a diameter of 324 mm Into the borehole 1 is mounted pulp-raising pipe 3 with a diameter of 245 mm, inside which set of air supply pipe 4, the pipe for supplying recycled water 5, the pipe coolant 6. On the well casing string 1 set sealed cap 9 with a pipe for supplying compressed air 10.
In the process of creating an underground reservoir feed steam through the pipe 7 at a temperature of 150°C with a flow rate of 1.5 tons/hour and additional water with an average consumption of 15 m3/hour. When the level change section air-water 11 in the development of tank 2 flow rate to anitelea water change from 0 to 30 m 3/hour.
As a result of heat exchange in the development of vessel 2 is thawing sand, which is deposited on the bottom of the underground tank. For airlifting rise through the pipe 4 from the compressor is supplied compressed air with a flow rate of 1500 m3per hour and circulating water through the pipe 5 with a flow rate of 85 m3/hour. The resulting slurry was raised by a pipe 3 to the surface and sent to a plant for dehydration. Dehydrated sand warehoused on the surface, and separated the circulating water pump through the pipe 5 returns in the production-capacity 2. To improve the performance of airlifting rise in the tip 9 wells 1 through the pipe 10 serves compressed air from the compressor, keeping the excess pressure in the well is equal to 0.2 MPa.
