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.
