摘要

Natural fractures have a significant effect on fluid flow and heat transfer in naturally fractured geothermal reservoirs. However, most previous studies have assumed that reservoir systems are either a single continuum or dual continuum model, while some studies have just considered a pipeline model. In this study, we developed a discrete fracture network (DFN) geothermal reservoir simulator. The DFN model developed was validated for synthetic fracture systems using a Tetrad; a comparison of the results revealed good agreement between two models. However, developed model is only a fracture model and cannot simulate fluid flow and heat transfer in the matrix. A matrix flow model will be added in the future.
