在前人对气井拟单相管流研究的基础上，结合井筒温度场分布模型，推导考虑动能项及摩阻影响的管流压降模型，可计算倾斜大管径拟单相流气井井底流压值。实例计算结果与压力计测试值平均绝对偏差仅为0．44％，满足工程误差范围要求，该模型可用于此类气井的井底流压计算。

Based on previous study of pseudo single-phase flow of gas well, combined with well-bore temperature field distribution model, this paper deduces the conduit flow pressure drop calculation model by considering the effect of kinetic energy team and friction. This method can be used to calculate the inclined big diameter pseudo single-phase flow of gas well＇ s bottom hole flowing pressure. The average absolute deviation of calculating results of the example and pressure test values is only 0.44%. This method can be applicable to gas well bottom-hole flowing pressure calculation.
