Abstract

A reasonably simple and comprehensive model of thermal conductivity of rocks is developed by generalizing the well-known effective-medium approximation model. This model allows one to take into account and quantitatively estimate the effect of various factors on the thermal conductivity of rocks. The factors include the shape and orientation of mineral grains and pores, anisotropy of thermal conductivity of minerals, structural-textural features, and fluid content, the number of mineral components being arbitrary. The experimental dependence of thermal conductivity on porosity is shown to provide constraints on the statistically average shape of pores and their orientation.
