| Abstract: | YCQ technique for reducing pressure and increasing injection has been used in water injection well B1233 to remove deep reservoir contamination and plugging and to increase injection.This paper introduces the composition of the string,deplugging formula study and application result.Field test showed that the injection pressure of well B1233 reduced obviously,water absorbing capacity increased,oil increment was notable in corresponding connected oil wells,and the injection profile was improved. |
