摘　　要：针对S油田过渡带外扩区块原油物性含蜡量高、含胶量高、黏度高以及凝固点低导致该区块油井易结蜡、频繁杆滞后等问题,S油田大规模应用了电加热清防蜡工艺技术,但电加热长时运行下单日单井耗电量高达696 kWh,年耗电费上千万元。为进一步降低生产运营成本,节约能耗,通过对电加热装置的运行制度研究,分析加热效果影响因素,运用井筒传热模型理论,计算电加热运行功率,建立电加热运行制度模板,以便于现场根据机采井实际工况,设定合理的工作制度。实施电加热运行制度调整后,单井能耗降低38%,实现高耗电设备节能运行。In view of the problems including high physical wax content,high glue content,high viscosity and low freezing point of crude oil in the extended block of transition zone for S oilfield,which leads to easy wax formation and frequent rod lag in the oil well of this block.S oilfield has applied the wax removal and anti-wax technology on a large scale.However,the electricity consumption of a single well in a single day under long-term operation of electric heating is as high as 696 kWh,and the annual electricity consumption is tens of millions of yuan.In order to further reduce production and operation costs and save energy consumption,the factors affecting the heating effect are analyzed through the research on the operating system of the electric heating device,and the shaft heat transfer model theory was applied to calculate the operating power of the electric heating.The operating system template of electric heating is established so as to set a reasonable working system according to the actual working conditions of the mechanical production well on site.After adjusting operating system of electric heating,the energy consumption of a single well is reduced by 38%,which realizes the energy conservation operation of high-power equipment.
