Instrumenting high reliability electric submersible pumps

摘要

An electric submersible pump (ESP) includes a motor and a sensor 328, 332 associated with a shaft 312 or rotor bearing 310 of section of the ESP string. A monitoring module tracks data from the sensor and a control module changes parameters of the ESP string based on the sensor data. Numerous properties of the ESP sting can be monitored, possibly by use of distributed fibre optic sensors.
