| 摘 要： | 潘谢矿区是安徽省淮南煤田重要的深部煤炭生产矿区,其石炭-二叠系煤系地层具有丰富的天然气资源。应用有机碳、热解、显微组分定量、等温吸附等实验分析数据,对潘谢矿区石盒子组煤系页岩有机质特征与含气量进行研究,并利用梯度下降算法建立了含气量与有机碳含量(TOC)和有机质成熟度(Ro)的多元线性模型。结果表明:潘谢矿区石盒子组煤系页岩TOC较高(平均为1.20%),有机质类型为Ⅲ型,成熟度Ro为0.75%~1.12%,处于成熟阶段,页岩含气量较高(平均为1.93 m 3/t)。多元线性模型表明,煤系页岩TOC和Ro的增加会有利于页岩气生成,但Ro对含气量的影响更为明显。

| Abstract: | The Panxie mining area is an important deep coal production area in Huainan coalfield,Anhui Province.Its Permo-Carboniferous coal measures strata possess abundant natural gas resources.Based on the experimental data of organic carbon,pyrolysis,macerals quantification and isothermal adsorption,the paper has carried out study on the Shihezi Formation coal measures shale organic matter features and gas content in the Panxie mining area.Using the gradient descent algorithm has established gas content,organic carbon content(TOC)and organic matter maturity(Ro)multivariate linear model.The result has shown that Shihezi Formation coal measures shale in Panxie mining area has higher TOC(average 1.20%),organic matter type belongs to category Ⅲ and maturity Ro is 0.75%~1.12%,thus in mature stage,The shale has higher gas content(average 1.93m 3/t.Through multivariate linear model has shown that the increasing of coal measures shale TOC and R o is propitious to shale gas generation,yet impact from Ro on gas content is more obvious. |
