摘要
综合国内煤层气井在压裂及排采技术上的相关研究,从余吾煤业S6、S7 井区的S6102、S7101、S7102、S7103工作面入手,对 50 口地面瓦斯抽采井进行了探索,针对压前作业情况、压裂施工情况、压裂过程评价、裂缝监测结果及压裂效果评价,对压裂工程质量及整体压裂试验展开研究,同时对排采技术及整体排采制度的建立进行了分析,对煤层气井整体压裂及排采技术的发展具有一定的借鉴和指导意义.
Abstract
Based on the relevant research on fracturing and drainage technology for coalbed methane wells in China,50 surface gas extraction wells were explored from S6102,S7101,S7102 and S7103 working faces in well area S6 and S7 of Yuwu Coal Industry Co.,Ltd.From the pre-pressure operation,fracturing construction,fracturing process evaluation,fracture monitoring results and fracturing effect evaluation,the quality of fracturing engineering and overall fracturing test were studied,and the establishment of drainage technology and overall drainage system was analyzed,which has certain reference and guiding significance for the development of integrated fracturing and drainage technology of coalbed methane wells.
