Abstract: To reveal the coalbed methane reservoir characteristics of Xiaolinhua coal mine in northern Guizhou, the basic geological conditions of structure,hydrogeology,coal-bearing property,reservoir and sealed condition were analyzed. The results show that the coalbed methane resources mainly occurred in the upper and lower coal measures,containing five layers coal,of which the cumulative thickness is large,the coal rank is No. 3 anthracite coal,and the original structure of coalbed is more complete. The coal reservoir is characterized by suitable burial depth,high gas content,strong adsorption and good pore connectivity,and the average coal reservoir pressure gradient is 0.87 MPa/100 m,average porosity is 2.95%,average permeability is 0.03 mD. The valuable suggestions are proposed for coalbed methane mining in target coal seam optimization,drilling technology, fracture technology and combined seam gas drainage technology. It is beneficial for coalbed methane ground development that the preservation conditions of high rank coalbed methane are advantage and the lower coal measures are better than the upper coal measures.

Key words: bioclastic shoal reservoir, microfacies analysis, facies-controlled inversion, facies-controlled porosity prediction
