煤层气系统——一种非常规含油气系统

Coalbed methane system:an unconventional petroleum system

为了更加有效地预测煤层气分布,指出煤层气有利勘探区域,引入了含油气系统来研究煤层气。煤层气系统是由煤层和其中的煤层气及煤层气藏形成所必需的一切地质要素和作用所组成的天然系统,其中的地质要素包括煤层及其顶底板,作用是煤层气的生成、储集和保存等。煤层气系统的建立和研究,为煤层气的勘探和开发提供了一种新的思维方式和研究方法,以及一套煤层气勘探研究的程序和框架。

To forecast the distribution of coalbed methane effectively and to point out the favorable area for coalbed methane exploration, the petroleum system is introduced to coalbed methane geology. Coal bed methane system is a natural system that encompasses coal seams and combed methane in them including all the geologic elements and processes. The essential elements include coal seams and surrounding rocks, and the processes are generation- reservoir- conservation of combed methane. The coalbed methane system is a new way of thinking and method. It offers a procedure and frame of coalbed methane exploration and research.
