Research And Application Of Fracturing Technology In Southern Qinshui Basin CBM Wells

The CBM is stored in the coal seam,which the main component is methane.the Coal bed gas wells must be fractured in order to be put into operation.The nature fractures are communicated by fracturing,simultaneously,the fracturing has removed near well zone pollution.Establishment of high seepage passage for coal bed methane desorption.Under the same conditions,there is a big difference in the gas production capacity of the coal bed gas well.Increase gas production is the core task.This paper analyzed characteristics and occurrence mechanism of coalbed methane reservoir.The reasons for the difficulties and failures of the coal bed gas well fracturing construction are determined.The main purpose of this paper is Optimized fracturing technology.The fracturing scheme suit the southern Qinshui Basin,and which can improve gas production capacity of coal bed gas well.
