摘　　要：本文聚焦于高凝原油的集输特性,对某油田从井口至转油站的原油集输流程进行了数值模拟分析,在双管掺水系统的基础上,利用PipePhase软件构建管网水热力模型。有效应对该集油流程中普遍存在的高耗电问题;通过调节掺水量、掺水温度等关键运行参数的优化策略,减少加热炉的耗电量。运用迭代算法精确计算出在不同掺水温度下,各井所需的最优掺水量。结合加热炉的基础运行数据评估不同方案下的总体运行成本。本论文为原油集输系统提供了一种切实可行的运行优化方案,为实现节能减排、降低运营成本的目标提供了有力支持。In this paper, focusing on the gathering and transportation characteristics of high-freezing crude oil, a numerical simulation analysis was conducted on the crude oil gathering and transportation process from the wellhead to the oil transfer station in an oil field. Based on the double-pipe water injection system, the PipePhase software was used to construct a water thermal model of the pipeline network. High-power consumption problem prevalent in this oil-gathering process is effectively addressed;the power consumption of the heating furnace is reduced by adjusting the optimization strategy of key operating parameters such as water injection amount and water injection temperature. An iterative algorithm is used to accurately calculate the optimal water injection amount required for each well at different water injection temperatures. Combined with the basic operating data of the heating furnace, the overall operating cost under different schemes is evaluated. This paper provides a practical operation optimization scheme for the crude oil gathering and transportation system and provides strong support for the goal of energy conservation, emission reduction and reduction of operating costs.
