分层压裂在煤层气开发中的应用

Application of Layered Fracturing in Coalbed Methane Development

水力压裂是储层改造的主要手段,对于邻近多储层的改造,分层压裂具有较好的效果。根据钻探、测井资料,分析了XS井的基本情况,进行了适用于XS井的山西组山22段和山23段的分层压裂工程设计,进行了小压测试和泵注模拟,并对其现场应用进行了分析。现场应用取得了较好的储层改造效果。

Hydraulic fracturing is the main means of reservoir reconstruction.For the reconstruction of adjacent multiple reservoirs,layered fracturing has a good effect.According to the drilling and logging data,this paper analyzed the basic situation of XS Well,carried out the layered fracturing engineering design of Shan22 and Shan23 of Shanxi Formation suitable for XS Well,carried out small pressure test and pump injection simulation,and analyzed its field application.The field application had achieved good reservoir reconstruction effect.
