Effect of Coal Dust on Coalbed Methane Wells Productivity

摘要：

　　CBM has the largest reserve except for conventional natural gas and is the cleanest energy.However,neither coal seam permeability nor CBM vertical well productivity has been determined when the immigration of coal dust are considered,which restricts the economic CBM exploitation.Based on coal seam characteristics,use permeability parallel path model and CBM seepage equation.The results show that with different ratio of non-clogging path and the total path,coal seam permeability and CBM vertical well productivity may either increase or decrease.
