Abstract

Abstract:

　The temperature drop of oil - gas gathering pipelines is mainly related to pressure drop and coefficient of over all heat transmission. The instability of flow along pipelines and the varieties of flow pattern lead to many differences in calculation ways of pressure drop. After taking into account the influence of the aver age gas ratio and Joule - Thomson effect on temperature drop , a mathematical model of oil - gas two - phase flow was established in the oil - gas gathering pipelines. The Baker flow pattern was adopted for evaluating oil - gas two - phase flow . Its result is superior to the result from Sukhov formula. It indicates that the method can increase the calculation accuracy of temperature drop o f oil - gas two - phase flow .

摘要： 油气集输管线的沿程温降主要与压降、总传热系数有关, 而油气两相流在沿程的流动过程中不稳定,流态多变, 导致了压降的计算方法有着很大的区别。在考虑了平均含气率与焦耳- 汤姆逊效应对温降的影响后, 建立了集输管线的油气两相流温降数学模型, 采用了贝克流型划分法对油气两相流进行计算, 其计算结果优于苏霍夫公式所计算的结果, 说明了该计算方法能够提高油气两相流温降计算的精度。
