Abstract

The coalbed methane (CBM) reservoir is the basic geological unit of CBM storing and CBM resource developing. The forming conditions of the CBM reservoir include coal thickness, coal rank, seam buried depth, caprock, and geological structure. The division of a CBM reservoir in the Huainan coalfield is mainly based on the geological structure form and seam buried depth. According to the Fufeng nappe and the secondary structures of Huainan synclinorium, seven CBM reservoirs are divided in the Huainan coalfield, such as Caijiagang, and the dynamic mechanism of CBM forming is analyzed. The structural position where the CBM reservoir is located has the important controlling role on the features of CBM reservoir.
