FIELD: oil and gas extractive industry.
SUBSTANCE: method includes consecutive pumping of isolating compound and cementing solution into the well, as well as pumping of buffer fluid into the well, pumping of buffer fluid is performed before isolating compound, and before pumping cement solution is treated by surfactant and dispersed by gas-like agent until receiving solution density in the well which matches density of bed water.
EFFECT: higher effectiveness of water isolation in fractured porous beds due to more reliable blocking of isolating compound in pit-face area of well with open shaft with large power value.
