Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] The invention is improved on the basis of the existing magnetic thermal wax-proof device. As shown in FIG. 2, the present invention includes a ring-shaped magnetic steel 3 fixed on the inner wall of the oil pipe 1 and a heating pipe 6 fixed on the sucker rod 8. Among them, the ring-shaped magnetic steel 3 is separated by a ring-shaped filler 4, and both ends of the ring-shaped magnetic steel 3 and the filler 4 arranged at intervals are fixed by a ring-shaped fixed block 2. The magnetic steel 3 is a neodymium iron boron magnetic steel, and the filler 4 is a non-magnetic non-metallic material. During the sucker rod 8 twitching process, the magnetic steel is protected to prevent it from breaking. The heating tube 6 is made of copper, copper alloy, aluminum, silver, etc. or other materials with high conductivity (relative conductivity greater than 60%, the higher the ...

Abstract

The invention relates to a magnetic-heating anti-plate device, wherein it comprises a heating tube sheathed on the oil pump rod and the magnet fixed on the inner wall of oil tube; the inner wall of heating tube has a metal tube with certain magnetic conductivity; and the neodymium iron boron magnetic steel will not degauss to prolong the service life. The invention can improve the oil flow via the magnetic function on the paraffin and the eddy heating of permanent straight generator, to reduce the pump resistance.

Description

Technical field [0001] The invention relates to a downhole wax removal and anti-wax device for oil production in an oil field, in particular to a magnetic thermal wax anti-wax device for oil production. Background technique [0002] Crude oil is a mixture of various hydrocarbons with complex composition. The crude oil in many oil fields contains paraffin wax. These paraffin waxes will naturally precipitate during mining and stick to the wall of the tubing. Over time, it will affect production and cause serious blockage of the tubing. Therefore, wax prevention and wax removal have become an important issue in petroleum exploitation. [0003] At present, the most commonly used anti-wax technology includes magnetic anti-wax technology. [0004] Magnetic wax prevention is a crude oil wax prevention technology. Its main principle uses high-performance rare earth permanent magnet materials as magnetic energy bodies to establish a stable and strong magnetic field to stimulate the paraff...
