METHOD OF OIL POOL DEVELOPMENT

摘要

processes of oil recovery from nonuniform reservoirs. SUBSTANCE: method involves alternation of injection of fringes of clay suspension and water. Method is distinguished by the fact that density of clay suspension in fringes is increased successively from 1050 to 1200 kg/cu.m. The method reduces water cutting of well products by 8.8-11.7% and increases well production rate by 55-65%. EFFECT: higher efficiency. 2 ex
