摘要
以左权县高家庄煤矿煤层气普查区内3#和15#煤层为研究对象,研究了该区煤层特征和煤级变化特征,并对煤储层含气性及储层特征进行了分析.结果表明,该区含煤地层地质条件简单,可采煤层厚度大、分布稳定;3、15#为贫煤～无烟煤,变质程度高,煤的变质程度自上而下随煤层层位的降低逐渐增大,煤层生气量大,煤的吸附能力较强;煤层含气量、渗透率等主要储层参数值较高,煤层含气饱和度接近饱和.
The No. 3 and No. 15 seams of CBM census area were studied from Gaojiazhuang mine in Zuoquan area. We discuss the growth characteristic of coal seams and the variation of the rank, fur- ther analyzes the gas - bearing and reservoir characteristics. And the results show that geological con- ditions of coal - bearing strata are simple, and minable coal seams are featured by big thickness and relatively stable distribution. Besides, the No. 3 and No. 15 seams belong to lean coal - anthracite coal, which is characterized by high metamorphic degree, coal metamorphic degree of coal gradually increased with the decrease of coal layer from top to bottom, gas content is targe and adsorption ca- pacity is high. The main reservoir parameter value of coal is higher, such as gas content, permeabili- ty, etc. Gas saturation of seams is close to saturation.
