摘要： A method for manufacturing an electrical cable provides an electrical cable suitable for use in heating wells. An elastomeric jacket is extruded over insulated conductors. A stainless steel plate is rolled around the jacket to form a cylindrical coiled tubing having a seam. The seam is welded, then the tubing is swaged down to a lesser diameter to cause the tubing to frictionally grip the jacket. A recess maybe formed in the jacket adjacent the seam to avoid heat damage from the welding process.

摘要： A method of heating gas being produced in a well reduces condensate occurring in the well. A cable assembly having at least one insulated conductor is deployed into the well while the well is still live. Electrical power is applied to the conductor to cause heat to be generated. Gas is allowed up past the cable assembly and out the wellhead. The heat retards condensation, which creates frictional losses in the gas flow.

摘要： A reinforcing interface between the stator and its housing in a progressing cavity pump is created from ribs extending inwardly into the stator from the housing inner wall that can be longitudinally oriented or spirally oriented. Alternatively, the housing wall can have grooves into the inner wall that are made more bulbous further into the housing wall from the groove inlets so that when filled with stator material a long and continuous grip is obtained with either the wall groove embodiment or the internal rib embodiment.

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： An electrical submersible pump assembly has a motor cooperatively engaged with a pump for driving the pump and a motor lead extending to the motor for supplying power to the motor. The motor lead has an electrical conductor enclosed within a tube. The tube is sealed from an exterior environment of the motor and contains a dielectric fluid. The motor may be filled with a dielectric lubricant and the interior of the tube of the motor lead may be in fluid communication with the dielectric lubricant. Alternatively, the motor may filled with a dielectric lubricant and the dielectric fluid within the interior of the tube of the motor lead may be sealed from the dielectric lubricant.

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 heater cable is strapped alongside tubing in a well to heat the production fluids flowing through the tubing. The heater cable has three copper conductors surrounded by a thin electrical insulation layer. An extrusion of lead forms a protective layer over the insulation layers. The lead sheaths have flat sides which abut each other to increase heat transfer. A metal armor is wrapped around the lead sheaths of the three conductors in metal-to-metal contact. Three phase power is supplied to the conductors, causing heat to be generated which transmits through the lead sheaths and armor to the tubing.
