摘　　要：【目的】煤层气储层的物性特征是进行煤层气开发研究的关键因子。【方法】重点对海孜煤矿深部勘探区域中组煤储层的物性参数进行调查,以对井田内中组煤储层物性特征进行研究。【结果】研究表明,煤层的物性特征适宜开采,其中有机显微组分占优,无机显微组分次之。该煤层含气量多,虽然煤层渗透率相对较小,但符合煤层气开采条件。煤层开采时的吸附作用一般,但有利于煤层气储集和缩短煤层气的开发周期。【结论】研究结果可为该研究区煤层气抽采提供可靠的技术参考。[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 showsthe physical properties of the coal seam are suitable for mining,with the organic microfractions predominant and the inorganic microfractions second.The coal seam contains a lot of gas and although the permeability 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.
