Numerical Simulation Study on Development of Geothermal Resource in the Borehole Wall Surrounding Temperature Field

摘要

Geothermal resource is a very clean source of energy, and its exploration and development has a history of almost one hundred years. In this paper, the mathematical model of multi-physical field on the platform of Comsol Multiphysics software was set up about the flow-solid-Thermal numerical model. During the analysis, rock porosity and permeability of stratum were taken into consideration to study change state of the temperature of export wells and injection wells. Besides, porosity-temperature curve fitting and permeability-temperature curve fitting were made respectively to study the relationship between the stratum temperature and permeability and porosity.
