FIELD: underground leaching. SUBSTANCE: well drilling, joining wells by hydraulic fracture, and pumping heated solutions in salt deposit. Pumped out solutions are evaporated. Exploring oil well is drilled and cased to water resistant rock laying below oil deposit, and a cavity is formed in them. Two pipes are lowered into the exploring oil well. Solution is heated by pumping cold solution in one pipe. Heated solution is pumped out through another pipe. The cavity is grouted and oil stratum is being shot after removing salts. EFFECT: high productivity. 1 dwg
