摘要
针对低压井在修井作业过程中因入井液漏失造成储层损害降低油井产能的问题,分析了入井液对储层损害的原因,在优化入井液体系、降低漏失量和防止二次损害三方面,有针对性的配套和完善了适合低压井修井作业的储层保护技术,在现场应用后,油井产能恢复时间比以前平均缩短了14d,取得了显著的经济效益。
Low pressure oil well can easily be damaged because of the leakage of incoming well fluid in the course of the workover job and its productivity may be reduced.Aimed at the condiction,the article analyzes entirely the damage reasons of the incoming well fluid to the reservoir and reservoir protection techniques suited for low pressure oil well workover iob are perfected from optimizing incoming well fluid system,inducing the leakage and preventing secondary damage aspect.The healing time of the low pressure oil well productivity is shorted fourteen days than ever and the remarkable economic benefits are obtained through field application of the reservoir protection techniques.
