【摘要】：介绍了国内外煤层气资源开发利用现状,分析认为"十三五"阶段我国煤层气开发的重点是地面煤层气开发。基于我国煤层地质条件及煤矿开采需求,介绍了地面煤层气开发中的压裂增透技术及煤矿区煤层气地面井抽采技术,分析了煤层气地面开发面临的政策和经济性问题,并提出相应建议。简述了地面煤层气利用方式,指出地面煤层气利用项目需要根据集输条件、气源规模和气源组成,选择恰当的利用途径。通过对地面煤层气开发利用情况分析,指出地面煤层气开发利用对提高煤层气利用效率具有积极意义,是未来煤层气开发利用的发展方向。
[Abstract]:The present situation of exploitation and utilization of CBM resources at home and abroad is introduced, and the emphasis of CBM development in China during the 13th Five-Year Plan period is analyzed. Based on the coal seam geological conditions and coal mining demand in China, this paper introduces the fracturing antireflection technology in the development of surface coalbed methane and the extraction technology of coalbed methane surface well in coal mine area, and analyzes the policy and economic problems facing the surface development of coalbed methane. The corresponding suggestions are put forward. This paper briefly describes the utilization mode of surface coalbed methane, and points out that the project of surface coalbed methane utilization needs to select the appropriate utilization way according to the gathering and transportation conditions, the gas source scale and the gas source composition. Based on the analysis of the development and utilization of surface coalbed methane, it is pointed out that the exploitation and utilization of surface coalbed methane has positive significance to improve the utilization efficiency of CBM, and is the developing direction of CBM development and utilization in the future.
