夏店区块中高煤阶煤层气扩散行为探讨

Discussion on the CBM Diffusion of Medium-high Rank Coal in Xiadian Block

随着煤层气开发产业不断扩大,煤层气单井产量未获得"质"的提高;在煤层气开发未取得突破性认识背景下,本文采用分子动力学方法,针对夏店区块中高阶煤煤层气扩散性质进行分析研究,探讨扩散对本区煤层气开发的影响。

With development of CBM industry,the production capacity of single CBM well cannot be improved with good quality.Under the background that the cognition of CBM development have not made a breakthrough,the paper analyzed and studied the character of CBM diffusion of medium-high rank coal in Xiadian Block though molecular dynamics method,and discussed the influence of diffusion on the CBM development in this area.
