稀油集输系统能耗分析与节能改造
|
摘要
随着油田开发进入中后期,油井产量下降、含水率升高,集输系统出现负荷率低、能耗高等一系列问题。以节能降耗为目标,针对辽河油田XLT集输系统,基于能量守恒原理建立了能量平衡"黑箱"分析模型,结合计量站、转油站、联合站的各项能耗评价指标,通过对站场能耗分布情况的现场测试,确定了能耗分布特点和用能薄弱环节,提出了各类站场主要用能设备的节能改造方案。结果表明,改造实施后,计量站年节气共2.16×10~5 m~3;转油站年节气共3.39×10~5 m~3,年节电共2.87×10~5k W·h;联合站年节气共2.34×10~5 m~3,年节电共3.04×10~5 k W·h。
In the middle and late stages of oilfield development, the production of wells declines and the water content rises. So a series of problems appear in the gathering system, such as low load rate and high energy consumption.Focusing on energy saving and consumption reduction, an energy equilibrium "black box" analysis model based on the principle of energy conservation was established for the XLT gathering system of Liaohe Oilfield. Combined with the energy consumption evaluation indicators of the metering station, the transfer station and the united station, through the on-site test of the distribution of the energy consumption of the station, the characteristics of energy consumption distribution and the weak links of energy consumption were determined, and the energy-saving retrofit schemes for the main energy-using facilities in various stations were proposed. The transformation results showed that the annual fuel saving of the metering station was 2.16× 10~5 m~3; the annual fuel saving of the transfer station was 3.39× 10~5 m~3, and the annual power saving was 2.87× 10~5 kW·h; the annual fuel saving of the united station was 2.34× 10~5 m~3, and the annual power saving was 3.04× 10~5 kW·h.
