摘要
煤层气储层描述是认识和评价煤层气储层的一项基本技术，通过储层描述建立煤层气储层地质模型，是煤层气有效勘探、优化开发的基础。根据煤层气及其储层的特点，将煤层气储层地质模型分为基础地质、煤岩学、吸附储集、储层物性及流体等五个特征进行描述。煤层气储层描述采用的是将煤层气地质学与储层工程相结合，静态与动态研究相结合的一套方法。该套方法在建立柳林煤层试验区４＃煤层地质模型过程中得到了应用，获得较好的效果。
Coal-bed gas reservoir description is a basic technique for recognizing and evaluating the coal-bed gas reservoir.Setting up the geological model of coal-bed gas reservoir through reservoir description is the basis of efficiently exploring and optimally developing the coal-bed gas.According to the characteristics of coal-bed gas and its reservoir,the geological model of coal-bed gas reservoir can be divided into five aspects,such as basic geology,coal petrology,reservoiring by adsorption,petrophysical property and fluid,etc.to describe.A set of methods of combining coal-bed gas geology with reservoir engineering and static behavior with performance were adopted in coal-bed gas reservoir description.These methods were applied in the process of setting up the geological model of coal bed No.4 in Liulin coal-bed test region,and a fairly good result being obtained.
