The invention relates to the technical field of petroleum and coal bed gas drainage exploitation devices, in particular to a submersible electric drive oil well pump which comprises an oil well pump assembly, a push rod assembly, a power assembly, a monitoring module and a central control module. Compared with a traditional submersible linear motor oil well pump structure, a pure mechanical structure is adopted for reciprocating motion, good environment anti-interference performance is achieved, a sealing guide sleeve is adopted for guiding, and the sealing guide sleeve is adopted for guiding. The stroke precision and the motor rotating speed can be effectively controlled through the central control module, the power consumption of the oil well pump can be effectively reduced, and the service life of the oil pumping system is prolonged. 本发明涉及石油及煤层气排液开采装置技术领域，尤其涉及一种潜油电驱抽油泵，包括抽油泵组件、推杆组件、动力组件、监测模块和中控模块，抽油泵组件、推杆组件和动力组件由上至下同轴依次设置，中控模块分别与所述监测模块和所述动力组件中的潜油电机相连，本发明主要作用在于相比于传统的潜油直线电机抽油泵结构的往复运动采用了纯机械结构，具有良好的环境抗干扰性，采用了密
