METHOD OF WELL PUMP PUMPING AND ELECTRIC SUBMERGIBLE PUMPING SYSTEM

摘要

method of heating subsea pumping systems. a system and method are provided for heating the fluid to be pumped by an electric submersible pumping system, the heat to heat the fluid can be inductively generated by adjusting the energy supplied to the motor of the pumping system. in one example, power adjustment includes supplying the voltage applied to the pump motor to a value lower than the voltage applied during normal operations. while decreasing the voltage the electrical frequency can be varied as well as the electrical waveform.
