ABSTRACT:
A recirculating gas separator for a submersible well pump includes a rotary gas separator for separating liquid to be directed to the pump from a gas. The separator includes a separating chamber, a well fluid inlet upstream of the separating chamber, and a liquid discharge outlet downstream of the separating chamber. A recirculating system recirculates a portion of the liquid discharged from the discharge outlet back to the separating chamber so that a gas-to-liquid ratio in the separator is substantially lower than a gas-to-liquid ratio of well fluid entering the well fluid inlet. Thus, the submersible well pump with the recirculating gas separator can successfully pump wells having substantially higher gas-to-liquid ratios than can be accomplished with prior devices.
