摘　　要：对彬长矿区多口煤层气直井钻井的地质、录井、测井、岩心等资料进行研究,识别出辫状河、曲流河、曲流河三角洲、冲积扇、扇三角洲和湖泊6种沉积相。随后分析了过去近七年间彬长矿区的煤层直气钻井质量、固井质量、压裂施工等环节的数据,研究认为沉积相会对煤层气直井施工进度、施工质量以及产气量产生重要的影响。该规律的总结有利于对彬长矿区后续的煤层气开发,以及对相近的陆相盆地煤层气直井开发提供经验。Research on geology data, drilling data, logging data of the coalbed methane vertical drilling data in Binchang mining area, 6 sedimentary facies have been found.These sedimentary facies are: braided river facies, meandering river facies, meandering river delta facies, alluvial fan facies, fan delta facies and lake facies. Then by analyzing the data of coalbed methane vertical wells on drilling, well cementing and hydraulic fracturing in the past seven years in Binchang mining area. The study shows that sedimentary facies have an important influence on coalbed methane well construction progress, construction quality and coalbed methane production. Summary of this law is helpful for understanding the subsequent coalbed methane development in the mining area Binchang, and provide experience for the study of the similar terrestrial basin coalbed methane vertical wells development.
