为实现“接转站—联合站—联合站—首站”四级布站的集输系统更安全、经济运行,以胜利油田某集输系统为研究对象,在工艺流程一定的情况下,考虑水力、热力等约束,建立基于联合站处理效果的集输系统整体运行参数优化模型,并采用随机试验法对模型进行求解。结果 表明:在满足外输原油含水率、污水含油量的前提下,与优化前相比,优化后的集输系统节约成本1 771 元/d、总能耗降低8.3%、集输系统效率提高4%,优化效果显著。研究成果可为油田集输系统的实际生产运行提供理论指导,降低生产能耗。(图3表4,参[23]

In order to ensure the safe and economic operation of the four-stage gathering and transportation system of “transfer station-united station-united station-initial station”, a gathering and transportation system in Shengli Oilfield was selected as the research object, and the optimization model for the overall operation parameters of the gathering and transportation system based on the treatment effect of the united station was established under the condition of a fixed process flow and considering hydraulic and thermal constraints. Random test method was used to solve the model. The results show that on the premise of satisfying the requirement of water content in crude oil and the oil content in waste water, the cost is saved by 1 771 yuan/d, the energy consumption cost is reduced by 8.3% and the efficiency of the gathering and transportation system is improved by 4%, demonstrating the remarkable optimization result. The research results can provide theoretical guidance for actual production and operation, further realizing energy saving during production. (3 Figures, 4 Tables, 23 References)
