煤层气储层作为煤层气开发的基础,通过收集以往的煤矿区勘查资料及煤层气勘探开发地质资料,分析高安建山-丰城曲江矿区煤层含气量和煤层气储层物性特征,从而判定煤层气储层发育情况。区内主要含煤地层为二叠系乐平组,且煤层发育,厚度稳定,从B4煤层的结构、构造、吸附性、含气性、孔隙性、渗透性、储层压力及盖层等方面,可以确定区内煤层变质程度较高,含气量较高,且封贮、储藏等条件较好。

Coalbed methane reservoir as the basis of coalbed methane development, by collecting past coal mine area exploration data and geological data of coalbed methane exploration and development, analyzing the coal seam gas content and physical characteristics of coalbed methane reservoirs in Gao'an Jianshan-Fengcheng Qujiang mine area, thus judging the development situation of coalbed methane reservoirs. The main coal bearing strata in the area are the Permian Leping Formation, with stable coal seams development and thickness. From aspects of the architecture, structure, adsorptive property, gas-bearing properties, porosity, permeability, reservoir pressure, cap rocks and so on of the B4 coal seam, it can be determined that the coal seams in the area have a high degree of metamorphism and gas content, good sealing, storage and others conditions.
