摘要
压裂缝高控制对煤层气井排采效果具有十分重要的意义。本文主要通过研究煤层气井压裂裂缝延伸机理,在分析沁水盆地煤层气储层的典型地质特征及岩心数据的基础上,结合实际压裂施工曲线和排采数据,总结出压裂缝高控制对煤层气井排采的影响机制,最后基于区块资料及施工经验提出几点压裂参数优化方法,为提高煤层气井产量提供更为有效的开发技术。
Fracture height control is important to the production of CBM well. This article mainly researches on the mechanism of fracture extension and analyzes typical geological characteristics and core data of CBM reserve in Qinshui Basin. It summarizes the effect mechanism of fracture height control on CBM production according to the actual fracture curve and production data. Several methods of optimizing frac- ture parameter are raised based on block data and construction experience, in order to provide more effective development technology which can boost CBM production.
