DISPLACING WATER TO THE EARTH'S SURFACE BY INJECTING GAS INTO A WATER SUPPLY DOME

Abstract

The article discusses the issue of pushing water to the surface by injecting gas into the dome of the water pressure system. The bed is completely filled with liquid. This requires the creation of under-ground gas storages in the central upper part of the water pressure system. For this purpose, the water must be pressurized from the drilled and unloaded wells. In solving the problem, a sequential approx-imation method is used, and the formation of the reservoir occurs due to the compression of the fluid through the operating wells. Fluids and gases that enrich the water pressure system, field system and parameters are known. The boundaries of the latter are the contours of the press and the flow. Accord-ing to the time, the water pressure in the reservoir has been determined by changing the sum of the volume of the cavity at the edge of the reservoir, the capacity of the created gas and the amount of injected gas. Under the conditions considered, the movement of water in the areas bounded by the contour of the discharge and flow can be considered as radial. Since this area is not very large, the elasticity of the water and the porosity of the environment can be ignored. This issue can be consid-ered as the filtration of incompressible fluid in a non-deformable bed. With a relatively small change in flow rate due to the constant pressure in the discharge circuit, the Water compressed by the gas flows freely through the mouth of the discharge well.
