煤系中的烃源岩为重要的生气母质，但由于煤系的韵律性或旋回性，表现出时间上短暂、层序上多变的特点，致使煤系烃源岩呈现多层叠置现象。煤系烃源岩母质生成的气体有多种称谓，概念的混淆给资源勘查评价带来诸多困难。基于地质和矿产经济学理论，从煤系烃源岩气体概念及成因联系出发，将煤系中的非常规天然气作为一个系统进行研究，揭示煤化作用-构造作用-地质环境条件之间的时空耦合关系，探讨区域地质背景与演化对煤系中气体形成的控制作用，形成特有的煤系气研究与资源评价路线。

The hydrocarbon source rocks in coal measures are important gas-generating resource matrix. However, due to the rhythm and the cyclicity, coal measures show the variability of short time and sequence, resulting in stacked multi-layers in hydrocarbon source rocks of coal measures. The gas formed in hydrocarbon source rocks of coal measures has various names. The confused conception has caused many difficulties in resource exploration and evaluation. Based on geology and mineral economics, from the relationship between the conception and the genesis of gas in hydrocarbon source rock of coal measures, the paper carried out research on unconventional natural gas by tak-ing it as a system, revealed the time and space coupling relationship among coalification, tectonism and geological environments, explored the control action of regional geological setting and evolution of gas formation in coal meas-ures, forming the unique path for research and evaluation of the gas resources in coal measures.
