摘要
针对锦州21-1油气田东营组储层部分油气井射孔段长、渗透率级差大、各小层受污染程度差别大的特点,采用了多氢酸酸液体系和泡沫酸分流酸化工艺相结合的酸化技术,进行酸化施工作业,取得了分流酸化、有效解除各层污染的良好效果,油气井达到了配产要求,合计日增油336m3,日增气22×104m3。
In view of that some wells in reservoir of Dongying Formation in Jinzhou 21-1 field have long perforation intervals with large differences of permeability and the damage degrees in subzones, we used the multi-hydrogen acid system and foamed acid diversion acidizing technology together for a- cidizing treatments and got good results of divert- ing the acid and removing the damage effectively, so that the wells reached the proration production, totally with 336 m3 oil increment and 22 × 10^4m^3 gas increment everyday.
