FIELD: oil-and-gas industry.
SUBSTANCE: invention relates to compositions for isolation of inflow of formation fluid in wells located in watered zones at pull-out of hole under conditions of abnormally low formation pressures. Proposed composition comprises 10 vol. % of water-repellant organosilicon fluid ("ГКЖ-11Н"), 85 vol. % of ethyl silicate "ЭТС"-40 as catalyst and 5 vol. % of diatomite as thickener.
EFFECT: higher efficiency of said jobs.
