针对文留油田在注水开发后期地层污染堵塞严重,近几年酸化效果偏低的情况,加强了对酸化标准的制、修订工作,从选井原则到对酸化的效果评价一系列操作流程,建立油水井酸化工艺标准体系,成立了酸化措施管理项目组,加大了过程监督。经过标准体系在酸化施工中一年来的应用,酸化效果得到了明显改善。

In view of the severe pollution and serious blockage of stratum at the post period of water injection exploration,as well as the low effect of acidification in recent years,the establishment and revision of standards are strengthened,together with a succession of operation process from the principle of selecting wells to the evaluation over the effect of acidification.Then the standard system of acidizing technology for oil-water wells is built up,while the project team for acidizing measure management is established,coupled with the enhancement of process supervision.Through the application of standard system to the acidizing operation for one year,the effect of acidification has been improved obviously.
