A COMBINATION PROCESS OF STERILIZING,DEPLUG AND FLOOD-INCREASING PROCESS WITH SODIUM HYPOCHLORITE / 微生物学通报

A new combination process of sterilizing, deplug and waterflood-increasing with sodium hypochlorite in waterflooding horizons has been developed. Its applicability was certified by 4 treatments of injection wells. After treatments the water-intake capacity of injection wells was increased, the pressure at well heat was decreased, and the average duration of stability wster injection was 307 days.
