摘要
FIELD: oil-gas producing industry; applicable in restriction of formation water inflow to well, and some other operations involved in well construction and operation. SUBSTANCE: method includes injection of composition based on hydrocarbon fluid with addition of surfactant. Said addition is injected together with the first portion of hydrocarbon fluid, and injected with the last portion of hydrocarbon fluid is rubber crumb. In this case, formation pressure gradient is periodically increased and well is allowed to stand for at least 72 h. Surfactant is added in excessive concentration to ensure composition surface tension on hydrocarbon-formation water interface not more 2•103 N/m. EFFECT: higher efficiency of operations involved in bottom water shutoff to porous-fractured reservoir. 3 cl, 1 tbl
