Abstract

The thermally induced fracturing appeared in the boundaries of mineral grains of rocks due to the different thermal expansion of different minerals while heating the rocks. When the microscopic fracturing connected like a network, the macroscopic permeability and the fluid transport properties of the rock changed remarkably. The implication of thermal fracturing to petroleum industry, earthquake process and transport modeling have been discussed.
