• Xinjiang's coalbed methane resources are 7.51×1012m3, accounting for about 25% of the country's total. Among the 10 basins with 1×1012m3 of coalbed methane resources, Xinjiang accounts for 4 of them. During the "13th Five-Year Plan" period, the target production of Xinjiang CBM was 3×108m3, and the actual production was 0.82×108m3, only 27.45% of which was completed, far lower than the planning expectation. The actual situation and result orientation reflect that Xinjiang CBM industry is facing many difficulties. By reviewing the exploration achievements, development progress and current industrial development opportunities of Xinjiang coalbed methane industry, the author analyzes the problems that hinder Xinjiang coalbed methane industry from five aspects: structure, depth, marginal resources, coal mine gas utilization status and coal measure gas resource potential, in order to help the coalbed methane industry to take advantage of the trend. Based on the analysis and study of successful cases of CBM exploration and development at home and abroad, combined with the current situation of this region, it is revealed that the work priorities of CBM in Xinjiang during the 14th Five-Year Plan period are as follows: First, through the application of data system in the old area, the construction and retention of physical data in the new area, the integration of geology and engineering, the innovation of working methods, the quality control of horizontal Wells, the optimization of reservoir transformation technology, the quantification of reservoir transformation effect, and the verification and promotion of new achievements, the shallow coalbed methane geology and engineering technology are consolidated, deepened, optimized and improved through the efforts of seven aspects. It lays a foundation for developing deep coalbed methane resources. Second, through the use of "marginal resources", old well transformation, old well deep side drilling, old well creative structure combination measures, 4 aspects of low cost production; Adopt the measures of "upper coal and lower gas" and "gas before coal" to promote the coordinated development of gas control and coal bed methane development.
