大地热流一定的情况下,沉积岩热导率对热流在含油气盆地中的传递及地温的分布有重要影响。目前国内外主要从岩石组构、孔隙度、含水饱和度、渗透率、温度和压力等方面对沉积岩热导率的影响进行了研究。通过对前人研究成果的综合分析,认为目前在含油气盆地中沉积岩热导率的研究中,沉积岩平行层面和垂直层面方向上孔隙连通差异特征与热导率关系和有流体存在状态下的沉积岩传热方式的研究相对较为薄弱,建议应加强这两方面的研究。
Under the condition of certain local heat flow, the thermal conductivity of sedimentary rocks has an important influence on the transfer of heat flux in the petroliferous basins and the distribution of geothermal temperature. At present, the research on the thermal conductivity of sedimentary rocks is mainly from the aspects of rock structure, porosity, water saturation, permeability, temperature and pressure. Through the comprehensive analysis of previous research results, it is considered that in the current research on the thermal conductivity of sedimentary rocks in petroliferous basins, the relationship between the difference in pore connectivity and the thermal conductivity in the parallel and vertical sedimentary rocks and in the presence of fluids The study of heat transfer method is relatively weak, suggesting that the two aspects should be strengthened.
