摘要
沁水盆地是我国煤炭的重要基地之一 ,也是煤层气勘探开发的重要有利区块。在整合前人研究成果的基础上 ,对沁水盆地煤层气成藏史和烃类气体 (主要以甲烷气体 )C、H同位素的“指纹”信息进行对比 ,初步探讨了煤层气形成的烃源岩性质和热成熟度 ;对沁水盆地煤层气是否具有多源复合特征进行了分析 。
Qingshui basin is not only one of important coal production bases in China, but also an important potential block for coalbed gas production. Based on previous study results, the history of gas generation, the information concerning C,H isotope of coalbed gas are researched.This paper primarily discusses the characteristics of hydrocarbon-source rock and thermal maturity, analyzes the possibility of multi-source property. At last the paper provides the new recognition on gas genetic types of the basin.
