摘　　要：两年多来,针对川中磨溪气田雷一～1气藏储层特征,进行了低渗改造攻关。采用了基岩酸化、前置液酸压裂、胶凝酸酸压裂和加砂压裂等工艺措施。经过效果分析及评价,认为酸压裂如加砂压裂优于基岩酸化。建议磨溪气田酸压裂要重视控制酸滤失和缓速;加砂压裂要改进压裂液性能和交联方式。Aimed at the reservoir characteristics of Lei-1 gas pool in Moxi gas field in the middle part of Sichuan, the reforming work on low permeability has being done in recent two years. The technology measures of bed rock aciding, preflush and gelling acid fracturing, as well as sand fracturing etc. are used. Through effect analysing and evaluating, the acid and sand fracturings are considered to be better than bed rock aciding. It is suggested that acid loss and slowing acid injected speed should be noticed; the sand fracturing should be improved in fracturing fluid properties and crosslinking way.
