METHOD FOR CONTROLLING OVER DEVELOPMENT OF OIL DEPOSIT WITH STRATA OF VARIOUS PERMEABILITY

摘要

FIELD: oil production. SUBSTANCE: with stratum temperature ranged within 70 - 90 C or as a result of preliminary stratum heating up to this temperature water solution of carbamide and ammonia salt is pumped in the stratum. Concentration of the substances provides formation volumetric gel just in the stratum. EFFECT: controllable oil production. 2 cl, 4 dwg, 2 tbl
