英文摘要：

Steam flooding is a new oil production method and adopted by many heavy oil fields. It is difficult to evaluate steam injected efficiency. Based on fluid mechanics and heat transfer theory, a mathematical model to simulate thermal field in steam flooding field was derived. Through numerical simulation, thermal field change of R2-21 steam flooding well group in Gudong oil field was simulated. The results can provide theoretical guidance to steam injection evaluation and well pattern optimization.
