Abstract
In order to have knowledge about the characteristics of coalbed methane in Qinshui basin clearly,based on the summary of the results of the basin research,this paper analyzes the factors influencing the enrichment of coalbed methane in No.15 coal seam of the basin.The main factors include the burial history,the formation of coal and rock,the hydrodynamic condition and the roof property.Buried depth,high vitrinite content,weak hydrodynamic conditions and compact rock capping are favorable to coalbed methane enrichment.The distribution of coalbed gas enrichment is divided into 8 types in this paper,the syncline area where is covered by mudstone or limestone is in favor of CBM preservation,the fault area and monocline area where are covered by sandstone go against CBM preservation.The anticline area where is covered by limestone and faut area are in favor of develpoment of CBM,are potential favorable mining area.关键词
