摘要：根据威宁地区钻探揭露情况,结合测井等资料,通过有机地球化学测试分析、核磁共振、电镜扫描和岩芯解吸实验,对黔西威宁地区煤储层特征及含气性进行分析。研究表明:煤层热演化程度较高,显微组分以镜质组为主,宏观煤岩类型主要为半亮煤,煤层孔隙和裂缝较发育,以溶蚀孔、粒间孔为主;泥页岩孔隙中介孔对总孔容的贡献远远大于大孔和微孔,祥摆组煤系页岩显示出较好的含气性,超过评价开发的最低标准。
Based on the data of drilling and logging in Weining area,the coal reservoir characteristics and gas bearing capacity are analyzed by means of organic geochemical test,nuclear magnetic resonance,electron microscope scanning and core desorption experiments.The results show that the thermal evolution degree of the coal seam is relatively high,the macerals are mainly vitrinite,the macro coal petrographic type is mainly semi bright coal and the pores and fractures of the coal seam are relatively developed,mainly consisting of dissolution pores and intergranular pores.The contribution of pore medium pore of shale to total pore volume is far greater than that of macropore and micropore.The coal shale of Xiangbai formation shows good gas bearing property.Exceeding the minimum standards for evaluation and development.
