Abstract: Optimization study on energy utilization of threephase flow in circular gathering pipeline network establish physical model of circular gathering pipeline network and temperature drop model of threephase flow in tube, built with a minimum energy consumption as objective function of the mathematical model, and analysis the relationship between the changes of water content, temperature and pressure and total energy consumption, finally find out the main factors affect the total energy consumption, secondary factors and the minimum factors were temperature, flow rate, pressure, and get the optimal scheme and pipeline total energy consumption. In the actual production process to reduce temperature so that the total energy consumption minimum. 

Key words: Threephase flow,      ,  Circular gathering pipeline network,    ,  Energy utilization,    ,  Total energy consumption,   ,  Optimization

摘要： 三相流环状集输管网能量利用优化研究是通过环状集输管网的物理模型、 管内油气水三相流之间的 温降模型, 建立了以最小能耗为目标函数的数学模型, 分析出了掺水量、 温度、 压力与总能量消耗之间的变化关系, 找到了影响总能耗的主要因素、 次要因素及最小因素分别为掺水温度、 掺水流量、 压力, 并得到管道总能耗的最优方 案。在生产实际过程中尽量降低掺水温度以使总能量消耗最少。
