Disciplinarian Of Distribution About The Reservoir Pressure In Southern Qinshui Basin

Coal-Bed Methane is a clean and efficient new energy sources, which also can be used aschemical raw material. Exploration and development of this new energy sources is of greatpractical significance to alleviate China's energy supply and demand, implement sustainabledevelopment of energy strategy and solve security issues in coal mining and so on. However,it is necessary to research China's coal-bed methane reservoir parameters deeply andmeticulously to achieve a major breakthrough in coal-bed methane exploration anddevelopment.In this paper, as the research object is southern Qinshui Basin, the southern QinshuiBasin coalbed methane reservoir pressure distribution regularity and influence factors areanalyzed according to the basic characteristics of coalbed methane reservoir, which is basedon the current coalbed methane reservoir parameters of the injection / fall-off well and thehydraulic fracturing theory and experiment equipment to test the southern Qinshui Basincoalbed methane reservoir parameters. First, to analyse basic characteristics of coalbedmethane reservoir, mainly including pore characteristics of coal-bed methane reservoir,isothermal adsorption and mechanism of gas production characteristics of coalbed methanereservoir and the basic characteristics of coalbed methane reservoir pressure; Secondly, tointroduce the coal seam Gas reservoir parameters of the laboratory equipment and analyseactual test-site conditions, primarily about coalbed methane reservoir injection / fall-off welland the hydraulic fracturing experiment principle and testing process; and apply it to the testwells in southern Qinshui Basin. Then use coal-bed methane injection / fall-off well and thehydraulic fracturing experiments to test the test wells of the southern region in Qinshui Basinand reach parameters of 55 wells 84-layer seam in southern Qinshui Basin coal-bed methane; Finally, according to the measured reservoir pressure in the southern Qinshui Basin to analyseoverall region, and it reaches distribution regularity of the southern Qinshui Basin coal seamreservoir pressure and factor of coalbed methane reservoir pressure. Thus it provides a moreaccurate and reliable reservoir parameters for exploration and development of the southernQinshui Basin coal-bed methane. This paper is of some reference and learn to China's coalbedmethane reservoir parameters'analysis.
