Thermal conductivity of gas-bearing shale of the Longmaxi Formation in the southern Sichuan

  • 摘要: 以川南龙马溪组深层含气页岩为研究对象,开展了页岩热导率及其配套实验研究,以探索深层含气页岩热导率特征及其影响因素。实验结果显示,川南龙马溪组含气页岩热导率主要分布在2.0~3.0 W/(m·K)之间,实测最大值为5.15 W/(m·K),最小值为1.22 W/(m·K),平均值为2.50 W/(m·K)。在此基础上探讨了川南龙马溪组深层含气页岩热导率与矿物组分、孔隙度、TOC以及温度的关系,深入分析了含气页岩热导率的影响因素。页岩的热导率与矿物组分密切相关,其中黄铁矿和石英是对热导率影响较大的矿物;热导率随页岩储层孔隙度的增加而降低;随TOC含量的增大而降低,且在TOC较低时热导率下降得快,在TOC较高时热导率呈缓慢下降;温度是影响热导率最主要的因素,受页岩的TOC含量制约,当TOC含量较低时,热导率随温度的升高而降低,而TOC含量较高时,热导率随温度的升高而升高。
