FIELD: oil and gas production.
SUBSTANCE: method of water influx insulation and well thief zone includes simultaneous separate pumping of two flows to the well, which consist of water insulation composition components. One of the flows includes clay drilling fluid, ethyl acetate and neonol at the following component ratio, vol %: clay drilling fluid 93.45-95.45, ethyl acetate 4.5-6.5, neonol AF 9-12 0.05, the other - high modulus soluble glass 100 vol %, and after the above flows are pumped, buffer of fresh water and cement grout is pumped consequently.
EFFECT: increasing efficiency of well thief zone insulation.
