Oilfield development has entered the middle and late stages, and it is a common phenomenon for formation energy attenuation to cause oil wells to lose their self-injection capacity. Artificial lift technology drives downhole equipment through external power to establish a continuous flow channel of crude oil from the reservoir to the ground, which has become a key technical means to maintain oil and gas production. Artificial lift technology is essentially a scientific supplement to subsurface energy, which can effectively overcome mining obstacles such as insufficient reservoir pressure and fluid viscous resistance.
