Problems solved by technology
Under the condition of increasing the conductive cross-sectional area of the conductor, the weight per unit length of the cable is reduced, and the tensile strength of the cable connected to the steel part of the hanger in the axial direction (cable length direction) is increased, which can effectively solve the suspension load-bearing problem. Avoid the problem that the diameter of the cable is not suitable for the inner cavity of the hollow rod

The invention relates to an apparatus for transmitting electric power to an oil production well by using a carbon-fiber composite-core aluminum conductor. The apparatus is characterized by comprising the carbon-fiber composite-core aluminum conductor connected with an oil pumping unit hanger and connected with two leading-out wires. The carbon-fiber composite-core aluminum conductor is wrapped in an insulated sleeve so as to form a cable wire. The cable wire is inserted into the inner chamber of a hollow rod of an oil pumping unit and is electrically connected with the inner wall of the bottom of the inner chamber of the hollow rod. The apparatus has beneficial effects of that the carbon-fiber composite-core aluminum conductor is used as an inner core of the cable wire and is used as a bearing body of the cable wire so as to solve problems of suspension tensile strength under a limited material sectional area condition and insulation between the cable wire and the hanger; a decrease in the mass density of a bearing material and a conductor material reduces the weight of the cable wire so as to further reduce the lifting power of the oil pumping unit and achieve consumption reduction and energy conservation.
Description
technical field [0001] The invention relates to a device for transmitting electric power down an oil production well, in particular to a device for transmitting electric power down an oil production well with a carbon fiber composite core aluminum stranded wire. Background technique [0002] In the electrothermal oil recovery technology, the intermediate frequency power supply is used to send the intermediate frequency voltage to the bottom of the hollow rod for electrothermal oil recovery through the cable, and the conductor of the cable wire is in contact with the bottom of the hollow rod. The hollow rod on the ground and the other side of the intermediate frequency power supply The poles are connected, that is, the hollow rod is used as the load of the intermediate frequency power supply, and the eddy current generated by electromagnetic induction directly heats the hollow sucker rod. [0003] With the later stage of oil well production, the depth of all heavy oil wells w...
