摘　　要：随着油田生产能源需求的不断增长,原油集输系统在能源供应链中所起的作用日渐显著,其能耗所占比重在整体油田生产中也日益增加,而系统能耗又受到多种因素的制约,如何科学合理地分析集输系统能耗影响因素成为油田面临的重要课题。同时,部分因素之间还会存在交叉影响而造成信息重叠,这给准确把握系统能耗主要影响因素带来较大难度。结合集输系统能耗构成特点和生产实际运行状况,综合考虑产液量、含水率、油品黏度等影响集输系统能耗的客观因素,采用改进熵权法、主成分分析法以及多元逐步回归分析法对各项因素的影响程度进行定量描述,根据权重大小进行排序,并将3种方法结合进行综合判定,确定含水率和产液量为影响油田集输系统能耗的主要影响因素,最后针对主要因素变量对系统的相关制约原因进一步深入探究,并提出系统具体降耗措施,以期为原油集输系统节能提效提供理论参考。With the growing demand for energy from oil fields,crude oil gathering and transportation system plays an increasingly significant role in the energy supply chain,and the proportion of its energy consumption in the overall oilfield production is also increasing.In addition the system energy consumption is affected by a variety of objective factors.Hence,scientifically and rationally analyzing the factors influencing the energy consumption of the gathering and transportation system is a significant challenge for oilfield operations.Furthermore,the interplay among some variables introduces information overlap,complicating the accurate identification of the primary factors influencing system energy consumption.This paper addresses the energy consumption characteristics of the gathering and transportation system in the context of actual production operations.It considers objective factors that affect energy consumption such as liquid production rate,water cut,and oil viscosity.To quantitatively assess the impact of each factor,the study employs enhanced entropy weight method,key component analysis,and multiple stepwise regression analysis.These methods are used to calculate the influence of each factor,rank them by their respective weightings,and combine the findings of the 3 methods for a comprehensive evaluation.Water cut and liquid production rate are identified as the main factors affecting the energy consumption of the oil gathering and transportation system.Finally,the study further explores main factors and variables of the system related constraints are,and provides recommendations on the system specific consumption reduction measures,in order to provide theoretical reference for the energy conservation and efficiency improvement of crude oil gathering and transportation system.
