摘要
我国低煤阶煤层气具有广阔的勘探和开发前景,但是低煤阶煤层气井产气量目前仅占煤层气产量的5%左右,主要原因是对低煤阶煤层气地质条件的研究不够深入。本文从煤层气成因、储层特征以及成藏条件等方面分析了低煤阶煤煤层气地质研究现状,以期更好地促进低煤阶煤煤层气开采工作的开展。
China's low-rank coalbed methane has broad prospects for exploration and development,but the gas pro?duction of low-rank coalbed methane wells currently accounts for only about 5%of coalbed methane production.The main reason is that the research on low-rank coalbed methane geological conditions is not deep enough.This paper analyzed the current status of low coal rank coalbed methane geological research from the aspects of coalbed methane genesis,reservoir characteristics and reservoir forming conditions,in order to better promote the development of low coal rank coalbed methane mining.
