苏里格气田完善压裂助排措施试验效果分析

Testing Effect Analysis of Completed Fracture Cleanup Measure in Su Lige Gas Field.

苏里格气田储层物性差、非均质性强、能量不足,大规模压裂排液效果较差,必须优化液氮伴注工艺、研制高效起泡剂,匹配液氮用量与施工规模。从苏里格气田排液现状、措施原理论证、操作方法、实施效果等方面入手,对2001-2003年苏里格排液效果进行了综合评价分析。

That of bad physical properly, high non-homogen and shortage of power in Sulige gas field makes the effect of big fracture cleanup is poor. So, tech of liquid nitrogen injection should be optimized, high effective foamer should be developed and quantity of liquid nitrogen and operation scale should be matched. From analyzing unloading situation, cause, treasure and theory, operating method and applied effect in Sulige gas field, the paper evaluates and analyzes the flowing back purpose from 2001 to 2003.
