FIELD: mining.
SUBSTANCE: invention relates to systems and methods for monitoring and controlling the operation of submersible pumping equipment, such as a submersible pumping unit with a linear valve electric motor. The circuit of a two-way power supply and a data set transmission from the submersible telemetry unit to the ground unit includes a set of inductive elements interconnected to form a zero point. The specified signal transmission circuit forms a circuit closed through the ground, which includes a submersible telemetry unit connected through the zero point of the three-phase winding of the linear electric motor and the zero point of the specified set of inductive elements with a ground telemetry unit and a control device. Also, the set of transmitted data includes at least the parameters of temperature and / or pressure of the well fluid, and / or the parameters of the force on the plunger of the submersible pump, and / or the parameters of the linear electric motor. Moreover, the data transmission channel contains at least one communication line with a data transmission frequency close to the power frequency of the linear submersible motor.
EFFECT: improved accuracy and expanded operational capabilities of the measuring system of a submersible pumping unit with a linear electric motor.
