【摘要】：为了对淮南地区煤系烃源岩特征作出评价,在采集相关样品的基础上对淮南煤田下石盒子组泥页岩样品的矿物特征和有机质的含量、显微组成以及成熟度进行了测试。结果表明:下石盒子组泥页岩中石英含量在35%左右;黏土矿物含量均值为56.28%。有机碳平均含量1.21%;干酪根以Ⅲ型和近于Ⅲ的Ⅱ2型为主,利于生气;样品的镜质组反射率均大于0.7%;生烃峰温基本高于445℃,有机质已进入成熟阶段。此外,多层煤层或煤线也为生烃提供了物质基础。综合评价认为,下石盒子组的烃源岩具有良好的生烃潜力,但较高的黏土矿物含量可能对后期的开采带来不利影响。
[Abstract]:In order to evaluate the source rock characteristics of coal series in Huainan area, the mineral characteristics, organic matter content, microstructure and maturity of shale samples of Xiashihezi formation in Huainan coalfield were tested on the basis of collecting relevant samples. The results show that the content of quartz in shales of Xiashihezi formation is about 35%, and the average content of clay is 56.28%. The average organic carbon content was 1.21; the kerogen was mainly type 鈪，
