FIELD: oil and gas production industry. SUBSTANCE: this is intended for preventing overflow of liquid in casing clearance. According to method, hydraulic fracturing of bed is effected by injecting fracturing liquid into bed. Injected initially is liquid with sedimentation additives. Used in function of this liquid is stabilized clayey water-oil suspension which is injected in amount sufficient for clogging fissures and restoring tightness of cement stone in hole clearance. Injection pressure is up to 0.9 of design pressure of bed fracturing. Amount of liquid with sedimentation additives corresponds to volume of fissures of untightness beyond casing string. Injection is carried out during period of time which is sufficient for penetration of liquid into aforesaid fissures. EFFECT: higher efficiency. 2 cl
