大庆油田永4转油站所辖油井产液量低、含水率高,集油能耗偏高.为降低集输能耗,建立了永4转油站各集输环节能量平衡模型,结合生产运行数据对其进行了能耗分析,确定了能耗分布规律及用能薄弱环节,并提出了主要用能设备改造、生产工艺参数优化等节能技改方案.节能预测结果表明:该集输系统改造后,可节约天然气48.97 m3/h,节电34 kW·h/h,能源效率可提高2.17％,节能效果显著.%The wells of Daqing oil field Yong 4 oil transfer station are in condition of low liquid production and high moisture content. This causes a high energy consumption of oil gathering. To reduce the energy consumption (it established the energy balance model of all aspects of Yong 4 oil transfer station gathering and transportation system. Combined with production data,it analyzed the energy consumption of gathering and transportation system. The energy consumption proportion and energy weak links were identifteded. The energy-saving technical reconstruction such as main equipments alteration and production parameters optimization were proposed. The results of energy-saving forecast show that Yong 4 oil transfer station gathering and transportation system is expected to conserve 48. 97 m3/h natural gas and 34 kW · h/h electricity after adjustment. Energy efficiency of station increases 2. 17% . The enenrgy-saving effect is significant.
