Wangying Coal Mining Area Sedimentary Environment and the Control of Coalbed Methane
In order to further study the coalbed methane enrichment of geological factors in WangYing mining area and then guide the development of coalbed methane, in terms of the evolution of the sedimentary environment from the coal, the use of sedimen-tology and coalbed methane geology principle and method analyses the research area of the formation of the coalbed methane control condition.Point out that the sedimentation of Gaode member of the Fuxin formation is mainly the shrinking of lakes - fan delta,other members are characterized by the deposition of alluvial fan - anastomosing river and marsh with alternate evolution.The microlitho-type of the coal seam is duroclarite formed in alluvial fan and the fan before the peat swamp environment;coalbed methane reservoir caprock is coverd by mudstone and silty mudstones of Shuiquan member of Fuxin formation that develop in the alluvial fan of distal Wetland -swamp facies sedimentary environment,with cover layer quality better -poor features from North West to South East.
