After reviewing the related literatures, the history and current situation of CBM mining in China are reviewed. Combined with the CBM mining technologies and research results that have been successfully developed in China, the existing problems in the existing technologies in China are analyzed from the perspective of drilling and completion engineering. Main Factors Restricting the Development Effect of Coalbed Methane. Actively carry out multi-layer drilling and drilling CBM, complex structure of stimulation and technical measures to increase production.This paper analyzes the technical difficulties in the process of drilling and completion in the coal seams in our country, the way to solve the problem and the technical measures to be taken.
