High temperature electric submersible pump motor and cooling device

Abstract

The application relates to the technical field of oil and gas exploitation equipment, in particular to a high-temperature submersible electric pump motor and a cooling device, which comprises a motor assembly arranged at the lower part of a pipe string and an active cooling assembly; a motor oil circulation cooling assembly is arranged in the motor assembly; the active cooling assembly is sleeved outside the motor oil circulation cooling assembly; the active cooling assembly comprises a flow guide pipe; the flow guide pipe is sleeved outside the motor oil circulation cooling assembly; the bottom of the flow guide pipe is closed; the lower part of the flow guide pipe is provided with a liquid inlet hole; the upper part of the flow guide pipe is provided with a liquid outlet hole and an exhaust hole; the active cooling assembly and the motor oil circulation cooling assembly can rotate along with the motor shaft of the motor assembly; in the rotating state, well fluid, dissolved gas and gas at the bottom of a well enter the flow guide pipe through the liquid inlet hole and are discharged from the liquid outlet hole and the exhaust hole, and in this process, the well fluid can continuously cool the motor oil circulation cooling assembly, so that the cooling effect of the motor oil circulation cooling assembly on the motor is improved.
