Abstract
Coalbed methane reservoir as the basis of coalbed methane development,by collecting past coal mine area exploration data and geological data of coalbed methane exploration and development,analyzing the coal seam gas content and physical characteristics of coalbed methane reservoirs in Gao'an Jianshan-Fengcheng Qujiang mine area,thus judging the development situation of coalbed methane reservoirs.The main coal bearing strata in the area are the Permian Leping Formation,with stable coal seams development and thickness.From aspects of the architecture,structure,adsorptive property,gas-bearing properties,porosity,permeability,reservoir pressure,cap rocks and so on of the B4 coal seam,it can be determined that the coal seams in the area have a high degree of metamorphism and gas content,good sealing,storage and others conditions.关键词
