METHOD FOR EXTRACTING CARBONATE OIL DEPOSIT BY MEANS OF PERIODICAL RESTORATION OF BED PRESSURE TO STARTING LEVEL

摘要

FIELD: oil extractive industry. ^ SUBSTANCE: method includes extraction of oil through product wells while force wells are stopped until bed pressure reaches level equal to 0.05-0.25 from starting bed pressure. Product wells are stopped and force wells are started into operation. Working agent is pumped through force wells until restoring bed pressure up to starting level. Further extraction of deposit is performed with continuous operation of force wells and periodical operation of product wells. Face pressure in force wells is supported at level of 65-75% of saturation pressure. ^ EFFECT: higher oil yield of deposit. ^ 1 ex
