METHOD FOR ISOLATION OF BRINE WATER INFLOW TO WELL

摘要

FIELD: oil production industry. SUBSTANCE: this can be used in oil wells during repair operations. Method ensures creation of efficient and simple to realize technological procedure which allows for reduction of oil bed permeability in water flooded interval, and to exclude operation of preliminary stopping of wells with abnormally high bed pressure, it also widens range of materials to be used for repair and isolation activities. According to method, injected into well are two reagents which interact with subsequent creation of sediment insoluble in water. EFFECT: higher efficiency. 1 tbli
