INTEGRATED HIGH-TEMPERATURE SUBMERSIBLE MOTOR

Disclosed in the present invention is an integrated high-temperature submersible motor, comprising a combined seal, a motor unit, and a circulating power cavity, which are sequentially connected, as well as a motor shaft passing through the three. The combined seal comprises a plurality of sealing units in series, the sealing unit being internally provided with an adjusting bag-mounting hole communicated with the outside, and the adjusting bag-mounting hole being internally provided with an adjusting bag. A blade guide wheel is mounted on the motor shaft located in the circulating power cavity. The combined seal is communicated with the circulating power cavity by means of a pressure pipeline. The motor in the present application satisfies a high-temperature well condition during heavy oil thermal recovery on an offshore platform, so that injection and production in the same well are achieved, thereby avoiding secondary rig operations. Meanwhile, on-site oil injection is avoided, thereby saving the operation
