摘　　要：根据油田特殊油井的排采需要,融合液压驱动技术、电气控制技术、自适应控制算法以及不规则运动曲线下的功图采集算法,研制了移动式液压抽油机自适应测控系统。该系统采用位置识别缓冲算法解决了储能式液压抽油机频繁换向带来的合流震动问题,满足了油田现场所需的运移机动性、安全性、智能控制、数据记录、状态监测等功能,作为对常规抽油机的一种补充,大幅节约了采油设备投资成本,减少了管理难度和管理费用,特别适用于油井的间歇排采作业。According to the discharge and production needs of special oil wells in oilfield,a self-adaptive measurement and control system for mobile hydraulic pumping unit is developed by integrating hydraulic drive technology,electrical control technology,self-adaptive control algorithm and indicator diagram acquisition algorithm under irregular motion curve.With adopting the position identification buffer algorithm.The confluence vibration problem caused by frequent reversing of energy storage hydraulic pumping unit is solved by the system.The function of migration maneuverability,safety,intelligent control,data recording,and condition monitoring and so on is satisfied.As a supplement to the conventional pumping unit,the investment of oil extraction equipment is saved sharply.The management difficulty and management cost are reduced.The system is especially suitable for the intermittent discharge and production of oil wells.
