摘　　要：针对常规抽油机井杆管偏磨的问题,结合细长筒状直线电动机,研究设计了一种利用直线电动机驱动的无杆采油技术。完成了采油工艺方法的设计,确定了抽油泵驱动系统的基本技术参数,设计了配套的单向作用管式抽油泵。在室内对直线电动机进行了耐压性能测试,结果显示该电动机耐压达到25MPa;对电动机进行了温升测试,电机在空载运行情况下,其温稳定值为35K,满足了现场的要求。对直线电动机的推力进行测试,结果显示推力达到20kN。在地面模拟井内对该采油系统进行了可靠性测试,测试结果为井口回压15MPa情况下机组正常工作500h,电动机可靠性较好,达到了进入现场试验的要求。Aiming at the problem of worn-out between rod and pipe,binding linear motor,a new technology of linear motor pump was designed for production system without rod.The engineer-ing was completed and certain work parameters were decided to design the single acting tube pump.A series of testing were proceeded,including pressure,temperature rise test,and working energy.When the linear motor works,the maximum pressurization is 25 MPa,supreme tempera-ture of motor is 35 K,the system fulfilled the condition of experiment.Motor testing of ener gydemonstrate,the maximum tension is 20 kN.The experiment of linear motor dependability is de-veloped in imitation well.After worked for 500 h,the linear motor production system is good,and it can be used in oilfield.
