Numerical Simulation Study of Geothermal Mining in Abandoned Wells Based on Finite Volume Method
In order to analyze the influence of different engineering parameters on the actual production of geothermal wells,a three-dimensional full-size model of formation-wellbore was established and numerically simulated by the finite volume method.Through the analysis of the model,the effects of inlet and outlet flow rate and inlet temperature on the outlet temperature and heat recovery power of geothermal wells were obtained.The error between the model and the actual working condition is within 5％.The results show that in the actual production process,the inlet temperature should be as low as possible and the inlet flow rate should be moderate to ensure that the efficiency of the geothermal well is maximized.
