Problems solved by technology
[0002] At present, in the petroleum industry system, oil extraction devices mainly include electric submersible pumps, screw pumps, and plunger pumps. The use of these pumps for oil extraction has its own advantages and disadvantages. Submersible pumps have large displacement and simple operation and management, but the initial investment is high. The energy consumption is also high; the initial investment of the screw pump is small, and the adaptability is wide, but the life of the pump is short and the failure rate is high
At present, ordinary beam pumping units using plunger pumps still dominate oil production. The technology is mature, the device is durable, and the failure rate is low. , the system efficiency is low, especially the high energy consumption
[0003] With the increase of well depth and production, and with the complexity of oil well production conditions (such as high viscosity, sand, gas, water flooding and strong corrosion, etc.), the disadvantages of rod pumping equipment become more and more obvious. The weight of the oil machine increases, the accidents of the sucker rod increase, and the displacement of the oil well pump decreases

Embodiment Construction
[0013] The present invention adopts a high-power linear permanent magnet stepping motor for the first time as a power system, which is composed of a double-acting plunger oil well pump and a motor protector. Due to the large driving force of the high-power linear permanent magnet stepping motor, low heat generation and high system efficiency, the high-power submersible linear permanent magnet stepping motor plunger pump system composed of it is shown in the appendix figure 1 . The linear stepper motor, referred to as LPM, is a drive device that converts the input electrical pulse signal into a micro-step linear motion. When an electric pulse is applied to this motor, it will move one step in a straight line and lock in the desired position accurately. Because its motion form is linear stepping, it is called linear stepping motor. Linear stepper motors can be widely used in various precision equipment, such as automatic plotters, computer equipment, intelligent instruments, r...
