摘要： An oil well cable for submerisble motors for use in medium to severe environmental conditions including high temperature, high pressures and/or chemical corrosiveness. The insulated conductor and/or groups or conductors are supported by exterior wrappings of felt about which is a supportive glass braid material. Further support is provided by a metallic armor wrap.

摘要： A gas separator interposed between a submersible pump and electric motor includes a plurality of flow diversion means including a coaxial impeller for impelling well fluid through a spiral gas separator chamber wherein entrained gas is centrifugally separated from the well fluid. The disentrained gas is subsequently returned to the well fluid basin while the well fluid passes from the gas separator chamber into the inlet of a submersible pump.

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.

摘要： A protecting unit interposed between an oil filled submersible electrical motor and a pump includes upper and lower chambers. The lower chamber is subdivided into a plurality of reservoirs connected in series to form a unitary passageway for oil expanding upwardly incidental to a temperature rise therein caused by actuation of the motor. The upper chamber communicates with the outermost reservoir of the lower chamber and includes a collapsible membrane disposed between and sealed to the upper and lower extremities thereof to define two pressure zones whereby changes in the volume of oil in one pressure zone results in an inverse change in the volume of well fluid in the other pressure zone.
