Integrated Fracturing and Drainage Technology for Coalbed Methane Wells:A Case Study of Yuwu Coal Industry Co.,Ltd.
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.
