摘要
对研究区15#煤层气储层特征进行了分析和研究,结果得出:15#煤层厚度大、含气量高;煤储层压力以略欠饱和为主;煤的孔隙度低,孔隙以微孔和过渡孔为主;煤中裂隙相对发育,但被无机矿物充填较甚,渗透率低;煤对甲烷具有较强的吸附能力、吸附量较大、吸收时间较短。研究结果以期为本区煤层气开发提供可靠技术参数。
No. 15 coalbed gas reservoir in the study area is analyzed and studied, the results showed that： NO.15 coal seam thickness is large, the gas content is high; the pressure of coal reservoir is slightly undersaturated; the coal porosity is low, is mainly the micropore and transition pore; the fissures in coal is relatively developed, and is filled by the inorganic,the permeability is low, coal has strong adsorption capacity, adsorption capacity, large absorption in a relatively short time of methane. The research results are expected to provide reliable technical parameters for CBM development in this area.
