摘　　要：为提高稠油井电加热系统的加热效率,解决油田中频电源加热运行控制主要依靠人工经验设置和低效的自动控制造成电能浪费的现状,本文设计了稠油电加热嵌入式控制装置。基于非嵌入式获取的油井生产电信号,以稠油开采电机的电功率为闭环反馈信号,获取油液最优温度的参考输入。在此基础之上,通过井口油液温度的微分反馈环节,改善温度迟滞效应,实现中频电源的节能优化控制。通过对嵌入式硬件核心电路模块的设计和主要软件功能的开发,不仅实现了稠油井电加热过程的动态控制,还实现了各项运行指标的现场及云端的实时监测。稠油井场试验分析表明,所设计的稠油电加热嵌入式控制装置符合井场节能安全的生产需求,节约能耗可达20%。In order to improve the heating efficiency of the electric heating system for heavy oil wells and solve the current situation that the heating operation control of the medium frequency power supply in the oilfield mainly relies on manual experience settings and low-efficiency automatic control resulting in electric power waste,an embedded control device for heavy oil electric heating was designed.Based on the non-embedded oil well production electrical signal,the electric power of the heavy oil production motor was used as the closed-loop feedback signal to obtain the reference input of the optimal oil temperature.On this basis,through the differential feedback link of the wellhead oil temperature,the temperature hysteresis effect was improved,and the energy-saving optimization control of the medium frequency power supply was realized.Through the design of the embedded hardware core circuit module and the development of the main software functions,not only the dynamic control of the electric heating process of heavy oil wells was realized,but also realized the real-time monitoring of various operating indicators on-site and in the cloud.The heavy oil well field test analysis showed that the designed heavy oil electric heating embedded control device could meet the production requirements of energy saving and safety in the well field,and the energy consumption was saved by 20%.
