The effect of sedimentary facies on coalbed methane in Binchang mining area

Abstract

Research on geology data, drilling data, logging data of the coalbed methane 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. By study of the CBM drilling, well cementing and hydraulic fracturing, Optimization parameter selection on the later CBM well engineering in different sedimentary facies had been summed up.
