A total of 348 bcm coalbed methane (CBM) resources are estimated to occur in coal layers with a burial depth smaller than 1500 m in Sichuan Province. Based on the working progress here, this paper divides the CBM gas exploration and development into five stages, including theoretical study, stratigraphic test well drilling, comprehensive study, exploration, and economic evaluation, then summarizes the achievements and experiences obtained in each stage, optimizes the working system, and analyzes the advantages and disadvantages, as well as the problems of CBM exploration and development. Finally, some proposals concerning policy, technology and industrialization of CBM are presented for further exploration and development of CBM in Sichuan Province.
