Oil field deep well oil production device

The utility model discloses an oil field deep well oil production device that little, the speed governing scope of giving out heat is wide, practiced thrift the electric energy. An oil field deep well oil production device, including the centrifugal pump, the centrifugal pump sub -unit connection has PMSM. Be equipped with oil and gas separator, protector between centrifugal pump and the PMSM from top to bottom in proper order. PMSM passes through cable junction with the vector control ware. The cable had better adopt latent oily cable. Owing to adopt the work of PMSM drive centrifugal pump, PMSM has power factor height, efficient, characteristics such as calorific capacity is little, speed governing scope width, can adapt to the demand that the liquid measure was produced to the oil well well, can prevent effectively that the motor from damaging because of generating heat. Because PMSM has the high -efficient district of broad, can improve system efficiency, saves a large amount of electric energy.
