摘　　要：煤层气是一种清洁能源,新时代对煤层气地质研究提出了新要求。基于对我国煤层气资源及分布特征分析,认为我国煤层气资源具有"多个煤阶、多个深度、多期生气、多源叠加、多期改造"的地质特征。受"三低一多"储层特征和储层非均质性影响,煤层气可采资源量比重低。当前煤层气地质研究中在控气条件评价与储层动态描述,深部煤层气勘探开发与关闭矿井煤层气利用,煤炭与煤层气资源协同勘查等方面存在不足。研究认为应建立适应我国复杂多变特殊地质条件的具有中国特色的煤层气地质综合评价技术体系,完善煤与煤层气(煤系气)协同勘查地质保障体系、构建关闭矿井煤层气资源综合利用地质评价与保障体系作为新时代煤层气地质三大研究方向。CBM is a kind of clean energy. The new era brings new demands on CBM geological research. Based on the analysis of CBM resources and distribution characteristics,This paper considers the geological characteristics of CBM resources in China as ＂multiple coal ranks,multiple depths,multiple phases of anger,multi-source superposition,multi-phase transformation＂. Affected by the ＂three low and one more＂ reservoir characteristics and reservoir heterogeneity,the proportion of CBM recoverable resources is low. Currently,there are outstanding problems in the research of CBM geology,such as CBM control condition evaluation and reservoir dynamic description,deep CBM exploration and shut-down coal CBM utilization,synergetic exploration of coal and CBM. There are three major research directions of CBM geology in the new era,which are to are to establish a comprehensive evaluation technology system for CBM geology with Chinese characteristics,to improve the coal geology and CBM（ coal gas） collaborative exploration geology security system,and to construct a geology evaluation and safeguard system for the comprehensive utilization of shut-down coal mines methane resources.
