摘要：In this article, we build coupled T-H-M models to solve the problem of thermalmechanical- hydraulic interaction in fracture-porous rock. The model that has been developed to illustrate the coupled process of thermal, hydraulic and matrix deformation. It includes the physical coupling between the fracture and the reservoir matrix when dealing with both thermal and water transport. Three modules have been assigned for representing this coupled behavior: the mechanical stress-strain module, Darcy’s fluid flow modules, and thermal conduction-convection modules. The flow and heat transport in the porous and the fractured phase are simulated by fluid flow and thermal modules while the single mechanical module represents the entire mechanical response of the dual porosity rock mass. ? 2016 Taylor and Francis Group, London.
