摘要： A clamp attaches an electric submersible pump cable to a sucker rod to deploy and support the cable in an oil well. The clamp includes a core portion having a bore extending axially through the core portion for receiving the sucker rod. A pair of arms extends radially outwardly from the core portion. The arms grip the cable on the facing surfaces of the arms for engaging the cable in a space between the arms.

摘要： An elongated cable structure of rigid and flat transverse cross-section for protecting conduits of various types includes interior axial lines of high tensile strength which may be used to suspend equipment from one cable end and to force the equipment axially past obstructions in a well hole. The structure may be raised and lowered in the well hole by means of exterior teeth which are firmly secured to the underlying tensile lines project from the surface of the structure to mesh with traction drives.

摘要： A cable structure includes a plurality of insulated conductors, an exterior jacket and at least one support member within the jacket and between the insulated conductors. Each support member is made of a material which has good thermal conductivity and which is rigid to resist crushing of the cable and damage to the conductors or their insulation. Variously shaped support members are disclosed.

摘要： A reinforced insulated electrical cable and a method of forming the cable, which is especially useful in oil wells. The reinforcement comprises a thin tape of thermosetting material imbedded with an open-mesh fabric, the tape being spirally wrapped directly around the cable's insulation. The tape is wrapped in unvulcanized form and is then vulcanized in place over the insulation. The layer of open-mesh fabric is spaced from the outer surface of the insulation so that, during vulcanization, the insulation can radially outwardly expand without contacting and thus deforming the fabric, and at the same time the insulation can push part of the thermosetting material through the spaces in the fabric.

摘要： An electrical cable especially useful in oil wells having a gas conducting channel beneath the outer sheath and a valved vent through the sheath to prevent explosive decompression. Gases entrained in the cable's insulation can exit from the insulation into the channel, move longitudinally of the cable along the channel and exit from the sheath via the vent. The cable comprises an insulated conductor, a low gas-permeable sheath surrounding the insulation, the gas conducting channel located between the insulation and the sheath, and the vent in the sheath and communicating with the channel. The channel can be formed of a plurality of filaments or fibers located closely adjacent one another to form a bundle. A plurality of bundles can be used, which can extend linearly or spirally along the insulation or in interwoven form.

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 cable for transmitting high voltage electricity for use with an electric submersible pump has a plurality of solid conductors for conducting electricity along the length of the cable. The solid conductors are uniformly and firmly bonded to the surrounding insulation with a thin bonding layer applied directly over the conductor. A layer of conductive fabric tape surrounds the insulation to form an outer stress control layer. The insulated conductors are surrounded by an extruded layer of lead. A second layer of fabric tape surrounds the lead. An armored outer layer surrounds the insulated conductors and the lead. Space between the insulated and wrapped conductors and the armored outer layer is filled with a jacket material.

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.
