The electric submersible pump consists of two parts: underground and wellhead. The underground part includes seven parts: the electric submersible pump, protector, separator, motor, lead cable, electric submersible cable, and underground sensor; The wellhead section includes the wellhead, junction box, control cabinet, transformer, and frequency converter.

Submersible oil pump is a multi-stage centrifugal pump composed of multi-stage impellers and guide shells. The structural form of the impeller and guide shell determines the displacement of the submersible pump, and the number of stages of the impeller and guide shell determines the head of the submersible pump and the power of the submersible motor.

The two-stage three-phase squirrel cage asynchronous motor is used in the electric submersible pump unit, which is the power source of the electric pump unit. According to fluid production, head, temperature, well fluid viscosity, and different specifications of casing, motors of different powers and diameters can be selected. The working voltage of submersible motors is generally 400-2500V, and the current is 30-120A

The separator can be divided into two types based on its structural form: rotary separator and settling separator. During the operation of the electric pump unit, the mixed liquid enters the separator for gas-liquid separation, and the gas enters the annular space of the oil sleeve for discharge to reduce the impact of gas on pump performance. The liquid is introduced into the submersible pump.

Transformers work using the principle of electromagnetic induction. By changing the number of turns in the primary and secondary coils, the purpose of changing the voltage can be achieved. The transformer in the submersible pump converts the grid voltage into the voltage required by the motor.
