摘　　要：以松河井田GP-2井为研究对象,基于气测录井资料获取了钻遇地层的含气性特征,并进行了含气层识别、分类与评价。结果表明:研究区煤层气资源主要赋存于龙潭组多个煤层及粉砂岩、细砂岩含气层中,且储层厚度及性质决定了气测曲线的异常形态。气测录井成果为松河井田煤成气勘探开发层段优选、煤层气与煤层间砂岩气兼探共采方案设计及压裂段产能贡献率研究提供了科学依据,对区域煤成气资源勘探开发具有重要的指导意义。Taking Well GP- 2 in Songhe Field as an example,the gas- bearing potential of drilled formation is obtained based on gas logging data,and the gas layers are identified,classified and evaluated. Results indicate that the coal- derived gas in the study area is mainly endowed in coal beds,siltstone and fine sandstone of Longtan Formation. The reservoir thickness and property decide the abnormal pattern of gas logs. The results of gas logging provide scientific basis for selection of CBM exploration and development layers,design of joint exploration and production of CBM and sandstone gas in coal beds,and productivity contribution through fracturing,which is of great significance to exploration and development of coal- derived gas resources.
