影响中国煤层气开发的科学技术问题分析

Analysis of the Scientific and Technological Problems in Developing China's CBM

在分析国外煤层气开发理论和技术的发展过程的基础上,针对我国煤层气开发的现状,提出了影响我国煤层气发展的主要的科学和技术难题,主要包括"硬煤"抽采理论和技术的精细刻画、结合井下瓦斯经验创新"软煤"抽采理论和技术。只有研究针对我国煤层气生成和赋存的物性条件的开采理论并指导开发实践才能推动我国煤层气产业的全面发展。

Based on the analysis of the theory and technology of foreign CBM developing process and faced the status of China＇s CBM development,the paper puts forward the major scientific and technological problems which affect China＇s CBM development,mainly including the precise characterization of drainage theory and technology in＂hard coal＂and the innovative drainage theory and technology in＂soft coal＂in combination with the experience in underground gas.Only by studying the development theory directed to the physical generating and storing condition for our country＇s CBM and guiding the practice can we promote the overall development of China＇s CBM industry.
