摘　　要：混输管路在油田的地面集输系统中应用日益广泛,而混输管路压降计算对于管路经济管径选取起决定作用。文中对气液两相混输管路压降计算简单总结,对均相流模型、分相流模型、流型模型的代表性计算方法进行了介绍,并通过具体工程实例对工程设计中常用的混输压降计算方法进行了对比。采用常用的多相流模拟软件进行校核,得出Beggs-Brill方法(流型模型)较杜克勒Ⅱ法(分相流模型)更接近多相流软件pipephase 9.0模拟结果。Multiphase flow has been used widely in the gathering pipeline in oilfields,and multiphase pipeline pressure drop calculation plays a decisive role in economic pipe diameter selection.The paper makes a simple summary of gas-liquid mixed transportation pipeline pressure drop and introduces the typical caluculation method of the model of homogeneous flow,the separated flow and the flow regime by giving a case example for comparing the mixture transportation pressure drop calculation method commonly used in the engineering design and checking the result by adopting the widely used multiphase flow simulation software.Finally it concludes that the computed values of Beggs-Brill method are closer to the result of pipephase 9.0 than Dukler Ⅱ method.
