WELLBORE ESP SYSTEM WITH IMPROVED MAGNETIC GEAR |
摘要 |
An electrical submersible pump system includes at least one electric motor coupled to a mechanism for hanging the pump system in a wellbore. At least one magnetic gear assembly is coupled at its input to an output of the at least one electric motor. A protector assembly is coupled at an input thereof to an output of the at least one magnetic gear assembly. A pump is functionally coupled at its input to a rotational output of the protector assembly. The protector assembly includes a tortuous path assembly having one end of each of a plurality of tortuous paths therein in fluid communication with fluid in the wellbore. The tortuous paths each have another end in fluid communication with dielectric fluid disposed within the protector, the at least one magnetic gear and the at least one electric motor. |
