Abstract FIELD: oil and gas production industry. SUBSTANCE: according to method, injected into absorption zone are coagulated wads which contain clay, filler and water. Additionally introduced in wads being coagulated are chlorous salt, polyacrylamide, soda ash at following ratio of components, mass%: clay, 26.4-28.0; filler, 1.7-1.8; usable as chlorous salt is chlorous salt of sodium or calcium, 0.87-2.8; polyacrylamide, 0.107-0.108; soda ash, 0.28; water, the balance. In this case, process of coagulation takes place in drilling pipes at simultaneous injection of aforesaid components. EFFECT: higher efficiency. 4 cl, 1 tblb
