Analysis of Physical Characteristics of Coal-Bed Methane Reservoirs in the Middle Group in the Deep Exploration Area of Haizi Coal Mine
[Purposes]The physical characteristics of CBM reservoirs are key factors in conducting CBM development studies.[Methods]The study focuses on the investigation of the physical parameters of the Middle Group coal reservoirs in the deep exploration area of the Haizi coal mine and investigates the physical characteristics of the Middle Group coal reservoirs in the well field.[Findings]Research show-sthe physical properties of the coal seam are suitable for mining,with the organic microfractions predomi-nant and the inorganic microfractions second.The coal seam contains a lot of gas and although the perme-ability of the seam is relatively small,it meets the conditions for CBM mining.The adsorption of the coal seam during mining is average,but it facilitates CBM storage and reduces the CBM development cycle.[Conclusions]The results of the study can provide reliable technical parameters for the extraction of CBM in this study area.
