Simulation Study on Microscopic Penetration of Coalbed Gas

Abstract:

The fracture system plays a very important role in the coalbed methane migration because they dominate the coal reservoir fluid flow. For this reason, determination of fracture permeability properties control mechanism for forecasting capacity is very important. This thesis fracture morphology of the role of coal-bed methane migration control, in single-phase flow conditions to simulate the fluid nature of the gas, the deduction of the macroscopic permeability, numerical calculations of the impact fracture surface morphology of permeability.
