    “双碳”背景下山西省煤层气勘探开发技术进展与展望

    Progress and prospect of coalbed methane exploration and development technology in Shanxi province under the background of carbon peak and carbon neutrality

    • 摘要: 山西省是煤层气资源大省,经过多年探索和发展,在煤层气勘探开发方面取得明显进展,初步实现了煤层气商业化开发。在“双碳”目标指引下,面向深部煤层、中浅煤层、煤矿区、煤系气共探合采等煤层气勘探开发时,由于对煤层气赋存特征、含气机制、压裂响应等关键地质与工程技术参数认识有限,因此制约了部分区块煤层气产能释放。概述了山西省煤层气勘探和开发现状,从深部煤层气、中浅层煤层气和煤系气共探合采3个维度分析了近年来山西省煤层气勘探和开发技术新进展,详细阐述了山西省煤层气产业在地质、钻探、压裂、排采等勘探开发过程中取得的技术突破。为了支撑山西省煤层气产业持续增储上产,提出了煤层气产业技术发展对策建议:一是加强煤层气基础地质理论研究;二是加大煤层气勘探开发工程技术攻关;三是加快煤系气共探合采立体开发。

       

      Abstract: Shanxi Province is a large province of coalbed methane resources. After years of exploration and development, obvious progress has been made in coalbed methane exploration and development, and the commercial development of coalbed methane has been initially realized. Under the guidance of the carbon peak and carbon neutrality goal, for the exploration and development of coalbed methane such as deep coal seam, medium-shallow coal seam, coal mine area and coal measure gas co-exploration and co-production, due to the limited understanding of key geological and engineering technical parameters such as coalbed methane occurrence characteristics, gas-bearing mechanism and fracturing response, the release of coalbed methane production capacity in some blocks is restricted. This paper summarizes the current situation of coalbed methane exploration and development in Shanxi Province, reviews the new progress of coalbed methane exploration and development technology in Shanxi Province in recent years from three dimensions of deep coalbed methane, middle and shallow coalbed methane and coal measure gas co-exploration and co-production, and summarizes the technological breakthroughs in the exploration and development process of coalbed methane industry in Shanxi Province, such as geology, drilling, fracturing and drainage. In order to support the continuous increase of reserves and production of coalbed methane industry in Shanxi Province, the countermeasures and suggestions for the development of coalbed methane industry technology are put forward: first, to strengthen the basic geological theory research of coalbed methane; the second is to increase the coalbed methane exploration and development engineering technology research; the third is to speed up the three-dimensional development of coal measure gas co-exploration and co-production.
