摘　　要：为了研究埋地热油管道输送过程中周围土壤温度场和输送原油的温度变化规律,对比商业油气管道流程模拟软件(SPS)、商业流场数值模拟软件(FLUENT)和自编程贴体网格算法的计算结果,在此基础上得到适合管道土壤温度场计算的方法。通过对比结果可以得知,贴体网格计算结果同FLUENT软件计算结果比较接近并且计算速度更快,预测管道最终温度低于SPS预测结果,对土壤温度场的计算考虑更加全面。In order to study the soil temperature field around the hot oil pipeline and the change rule of the hot oil, three kinds of meth ods, such as commercial oil and gas pipeline process simulation software（SPS）, commercial flow field numerical simulation soft- ware（FLUENT） and body-fitted grid programming（BFGG）, were compared. On the basis of comparison, a suitable calculation meth- od of pipeline soil temperature field can be found. By comparing the results of three methods, the soil temperature field of BFGG is almost the same as FLUENT, but faster than FLUENT, and the predicted oil temperature of the end pipeline is lower than SPS, which is on account of the calculation for soil temperature field con sidering more comprehensively.
