永4转油站集输系统能耗分析及节能预测

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 energy consumption analysis and energy-saving forecasts of gathering and transportation system of Yong 4 oil transfer station

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 identifieded.The energy-saving technical reconstruction such as main equipments alteration and production parameters optimization were proposed.The results of energy-saving forecast showed that Yong 4 oil transfer station gathering and transportation system was expected to conserve 48.97m3/h natural gas and 34kW•h/h electricity after adjustment.Energy efficiency of station increased 2.17%.The enenrgy-saving effect was significant.
