摘 要: | 目前在各大油田采油厂的生产中,管、杆偏磨成为一个不容忽视的问题,直线电机驱动潜油无杆泵的应用则可以有效解决这一问题。直线电机驱动潜油无杆泵是把潜油直线电机与动筒式抽油泵结合为一体的无杆采油系统,潜油直线电机直接驱动抽油泵,取消了机械传动部分,减少了功率损耗。潜油直线电机采用永磁同步直线电机,功率因数高,励磁电流小。抽油泵为上行程时吸液,下行程时排液的工作方式的新型动筒式抽油泵,适合潜油直线电机位于抽油泵下方的工作方式。

Abstract: | At present,it is an important problem that eccentrically wear occurs between sucker rod and tubing in most oil well,otherwise submergible rodless pump driven by linear motor can solve the problem effectively.The rodless oil pump system consists of submergible linear motor and oil well pump with reciprocating liner.Oil well pump is driven by linear motor directly and mechanical transmission assemble of gears and straps is abolished,so the system reduces the power loss.The motor is synchronization linear motor with higher power factor and lower excitation current.Oil well pump sucks oil in ascending journey of liner and lifts oil in descending journey of linear motor,so the pump adapts to the working condition when the linear motor is assembled below the pump. |
