METHOD FOR DEVELOPING OIL DEPOSIT OF HIGH INITIAL WATER SATURATION

摘要

FIELD: oil production. SUBSTANCE: well bottom pressure allowing bound water to enter the well together with oil is set for producing wells. Oil is extracted at well bottom pressure above the preset value. Producing wells are stopped, the pressure is restored and oil is extracted again after decreasing well bottom pressure. Oil may be extracted through horizontal wells. EFFECT: extraction of oil from oil collectors with low permeability. 3 cl
