摘　　要：双管拌热开采与其他稠油开采方式相比,在某些油藏条件下具有明显的优势。在稠油油田开采中,双管拌热开采占有很大的比例。双管拌热的热传导机理比单管注蒸汽开采复杂,给研究双管拌热开采时井筒温度的分布带来了困难,为此,建立了一种井筒伴热数学模型。通过给出的相应参数,进行了模拟计算和对比,其结果符合双管拌热及传热的实际情况。Dual tubing production with heat tracing has an obvious advantage in some reservoirs relatively to other production ways of heavy oil reservoir. This production way dominates a big proportion in the production of heavy oil reservoir. The mechanism of dual tubing production with heat tracing is more complex than that of single tubing production with steam injection, which brings the difficulty to the study of wellbore temperature distribution during the dual tubing production with heat tracing. The paper creates a mathematical model for wellbore with heat tracing. Through the mathematic simulation and comparison of given relevant parameters, the study results conform to the practice of dual tubing production with heat tracing.
