A Research on Seepage Mechanism to the Coal Seam Gas
As the existing conflicts between the consumption and supply of the conventional oil and gas will be inevitably aggravated, the coal seam gas as a kind of unconventional resource to utilize, by that offers a kind of clean, high-quality energy for development of national economy, and it also has the signification for alleviating the energy short supply state, which have achieved considerable economic and social benefits. A lot of seepage problems which are adsorption, desorption and migration are involved in the development of coal seam gas. The seepage characteristics and law of the gas in coal seam are discussed, the fluid-solid coupling interaction of gas and coal are analyzed, and the criterion of coal and gas outburst is presented. The trend in the study on the seepage problems in coal seam gas is come up in the end.
