Numerical Simulation Study on Feasibility of Coal-Bed Methane Reservoir Commingling in Qinduan Block

Coal-bed methane (CBM) is clean energy which owns currently the best prospects for development, its efficient development is conducive to the safety production of the coal industry. Commingling can effectively reduce the development costs of coal-bed methane, while improving the methane production. Aiming at the actual geological conditions in Qinduan block, using numerical simulation technology, establish the ideal model based on the actual geological data to make feasibility study of commingling respectively from the permeability and the initial reservoir pressure. The results show that, under the condition of reasonable control production system, the target block can be commingling.
