FIELD: oil production industry. SUBSTANCE: this can be used for treating bottom-hole zone of bed in injection and producing wells. According to method, separately injected are components of gel-formation compound, then pushing-through agent is injected and removed, and technological delay is made. Pushing-through agent is removed in smaller or larger volume than it is injected. Used as pushing-through agent is liquid not mixable with components of gel-formation compound and with viscosity higher than viscosity of gel-formation compound. Flow ratio of removing pushing-through agent is lower than its injection flow rate. EFFECT: high efficiency. |
