摘要： A submersible well pump motor has features to prevent the carrier bearing from sliding axially along the stator due to thermal growth of the rotor. The rotor has a shaft and rotor sections spaced apart from each other. Carrier bearings are located between the rotor sections, each having an anti-rotation member that frictionally engages the inner diameter of the stator to prevent spinning of the carrier bearing. A deflectable thrust washer may be located between ends of the carrier bearing and the rotor sections. The thrust washer reduces in thickness in response to an axial thermal growth force due to axial thermal growth movement of the rotor sections and shaft. The thermal growth force is less than an amount of dislodging force required to cause the anti-rotation member to axially move relative to the stator. Rather than deflectable thrust washers, sacrificial thrust washers that dissolve prior to normal operation may be used.

摘要： A power line for an electrical submersible pump has three metallic impermeable tubes. A single electrical conductor is located within each of the tubes. Each conductor has at least one elastomeric insulation layer surrounding it. An annular portion of the insulation layer of each of the electrical conductors is in tight contact with the tube to form a seal. The annular portions may be annular crimps formed in the tube at intervals. The annular portion could also be a continuous seal caused by swelling of the insulation layer due to contact with a hydrocarbon.

摘要： A system and method is provided for heating fluid to be pumped by an electrical submersible pumping system. Heat for heating the fluid may be inductively generated by adjusting the power delivered to the motor of the pumping system. In one example, the power adjustment includes supplying the voltage applied to the pump motor to a value less than voltage applied during normal operations. While lowering the voltage the electrical frequency may be varied as well as the electrical waveform.

摘要： An electrical line for installation in a well for transmitting power to a well pump includes a string of coiled tubing. An electrical cable having insulated electrical conductors embedded within an elastomeric jacket extends longitudinally through the interior passage of the tubing. Retainers are mounted to the electrical cable and spaced longitudinally apart from each other. An indentation is integrally formed in the tubing adjacent each of the retainers. Each indentation protrudes into the interior passage of the tubing and creates a ledge which is contacted by one of the retainers when the electrical line is installed in the well. The indentations and retainers transfer weight of the electrical cable to the tubing. Weld material is filled into the depression on the surface created by each indentation.

摘要： An electrical cable and a method for manufacturing the electrical cable are provided in which a plurality of insulated conductors have a protective jacket extruded thereabout, the protective jacket having an exterior ribbed surface which includes a plurality of longitudinally extending ribs between which extend a plurality of thermal expansion voids. The protective jacket is formed from a thermally set elastomeric material which is partially cured, and then a protective exterior armor is helically wrapped around the exteriorly ribbed surface of the elastomeric, protective jacket. Then, the electric cable is heated to an elevated temperature for a period of time which is sufficient for fully curing the elastomeric protective jacket formed therein.
