Abstract
The utility model discloses an electromagnetic and superconductive heating dewaxing device for a hollow sucker rod of a producing well, solving the problem that wax easily deposits on a mineshaft wall, namely, the hollow sucker rod of a thickened oil producing well. An armoring mineral insulation electromagnetic heating wire is placed in the hollow sucker rod of the producing well; superconducting fluid is filled in the hollow sucker rod; in the production process, the heat produced after the armoring mineral insulation electromagnetic heating wire is electrified is used for heating the superconducting fluid in the hollow sucker rod, the heat of the superconducting fluid is transferred to the outer wall of the sucker rod through the sucker rod and is used for heating crude oil in an oil pipe; when the heating temperature is higher than the wax deposition temperature, wax blockage formed in a mineshaft can be smelted; and due to the electromagnetic effect, walls of the sucker rod and the oil pipe produce repulsive interaction on waxiness to prevent the waxiness in the crude oil from adhering the surfaces of the sucker rod and the oil pipe, thus the motion resistance of the crude oil in the oil pipe is greatly reduced, and the burden and the fault rate of an oil well pump are reduced.
