摘要
流花4-1油田是我国第1个基于深水开发模式采用水下生产设施开发的油田,其电潜泵驱动电机与变频器之间的距离长达15.5 km,给电潜泵远程控制提出了挑战。针对电潜泵远程控制带来的风险,开展了流花4-1油田水下电潜泵远程控制系统研究和方案设计,最终选用PF7000型中压变频器控制系统成功解决了水下电潜泵长距离控制所面临的电机侧电压值偏离、电压变化率大、电机绝缘影响和输出电流谐振影响大等技术难题,实现了8口井水下双电潜泵一次性投运成功。远距离中压变频控制系统在流花4-1油田生产控制中的成功应用在国内尚属首次,可为我国海上其他油田水下电潜泵远程控制提供借鉴。
LH4-1 oilfield is the first one to be developed with subsea production facilities in deep water oil development pattern in China.The distance between the electric submersible pump drive motor and frequency transformer is up to 15.5 km in LH4-1 oilfield,and the long distance gives challenge for electric submersible pump remote control.In view of the risk brought by the remote control,the research and project design of the remote control system have been carried out for LH4-1 oilfield.Finally,POWERFLEX7000 control system has been selected to solve the technical problem of value deviation,voltage large change rate,the motor insulation effect and output current resonance effects.The results show that all 8 electric submersible pumps are successfully operated.The remote intermediate frequency transformer control system was applied for the first time in LH4 1 oilfield,and it can provide reference for application of electric submersible pump remote control in other offshore oilfields in our country.
