摘要： This abstract describes an improvement in down hole submersible oil pumps for pumping oil and gas mixtures, which includes a section in which the well fluid is given a helical motion within a first outer annular separation chamber, such that there is a physical separation between liquid on the outside and gas on the inside. The liquid passes onto a succeeding stage of impeller, while the gas and some liquid is returned to the first impeller stage through a second inner annular recycle chamber. The gas is vented from the inner chamber to the outside of the pump housing, while the liquid portion is recirculated through the first impeller.
