摘要:: 顺北油气田集输管网集输半径大、气油比高、地形起伏大、流态复杂，时常引起管道低洼处积液量大、段塞流等多种复杂工艺问题。为此，建立气液混输管网水力仿真计算模型，并利用顺北油气田现场数据对模型进行修正，进而开发油气混输管网仿真计算程序，对顺北1区集输管网气液混输特性进行仿真及参数预测。结果表明：建立的水力计算模型仿真结果与实测数据的误差基本在±6％以内，满足运行需求；管网各管道的持液率均较低，流型以分层流和环状流为主；针对管网中压降与温降较大、管输效率较低、积液量较大的管道分别提出了优化及保护建议。研究成果可为气液混输管网设计及安全运行提供技术依据。（图3，表7，参30）

Abstract:: The gathering pipeline network in the Shunbei Oil and Gas Field has the characteristics of large gathering radius, high gas-oil ratio, undulating terrain and complex flow patterns, which often result in complex process problems such as large amount of liquid accumulation and slug flow in the low areas of pipeline. Thus, a hydraulic calculation model of gas-liquid mixed transportation pipeline network was established by numerical simulation and corrected with the field data of Shunbei Oil and Gas Field. Thereby, a simulation calculation program was developed for the oil-liquid mixed transportation pipeline network. Further, the simulation and parameter prediction were performed for the gas-liquid mixed transportation characteristics of pipeline network in Shunbei Block-1. The result shows that the error between the simulation results of the hydraulic calculation model and the measured data is basically within ±6%, which satisfies the operation requirements. Besides, the pipeline sections in the network are at a low liquid holdup and in the main pattern of stratified and annular flows. Moreover, recommendations on optimization and protection were put forward for the pipeline sections with great pressure and temperature drop, low transportation efficiency and large liquid accumulation. Generally, the research results could provide strong technical support for the design and safe operation of gas-liquid mixed transportation pipeline network. (3 Figures, 7 Tables, 30 References)
