Abstract
The utility model belongs to a use at the oil field earth's surface, and be used for the defeated magnetism viscosity reduction of crude oil collection, drag reduction paraffin control device. In the industry, magnetic treatment of fluids has been used for a long time, and many devices for treating fluids by magnetic fields have been developed. However, these prior art devices are structurally limited and do not meet the requirements of surface crude oil gathering and transportation. The device is provided with permanent magnets arranged along the axial direction on the central axis, and is also provided with annular permanent magnets on the inner pipe, so that the magnetic field gradient of the realized magnetic field intensity is ideal. Meanwhile, due to the reasonable structure, the device has value suitable for being applied to surface crude oil gathering and transportation processing.
Description
The invention belongs to a kind of to be used on the face of land, oil field, and is used for the magnetic viscosity reduction drag reduction wax-proofing apparatus of crude oil transmission.
When crude oil flows in pipeline, usually there is paraffin to be deposited on the tube wall gradually, thereby causes the crude oil flow resistance to increase, final blocking pipeline.Having done a large amount of research round the paraffin people that how to remove deposition explores, usually adopt the paraffin on that heat is washed or the mechanical method removing tube wall, but it is too high to do cost like this, through further discovering under certain conditions, adopt magnetic field device, crude oil is handled, the disperse in crude oil of crude oil wax crystalline substance is distributed, reduced solidifying point, viscosity and the flow resistance of crude oil.
In fact, industrial, with the magnetic field treated fluid very long history has been arranged, as can reduce or prevent the harm of incrustation scale with the magnetic field treated industrial water, can improve its combustion efficiency with magnetic field treated fuel oil, reduce to pollute etc., developed the device of many magnetic field treated fluids with the method for the magnetic field treated fluid people that adapt, these devices are more representational Chinese patent CN86202462; U.S. Pat 2652925, US3228878, US3349354, US4707255 etc.Yet these above-mentioned devices owing to be subjected to structural restriction, make it can not satisfy the requirement of face of land crude oil transmission magnetic treatment.The invention is exactly produce for the above-mentioned deficiency that overcomes existing device for magnetic treatment for fluid a kind of rational, the magnetic viscosity reduction that can use in the ground surface crude oil transmission, drag reduction wax-proofing apparatus.
Technological points of the present utility model is: install an end lap joint flange is housed, purpose is to be convenient to mounting or dismounting, and lap joint flange is made up of movable end (11) and fixed end (12).Device is tubular shape, can arrange the every capable permanent magnet of several rows permanent magnet in pipe vertically as required can be made up of some joint magnet, it is corresponding that the end face magnetic pole of every block of permanent magnet on each row wants homophase to face the end face magnetic pole of corresponding magnet of delegation, both magnetic poles are opposite, as shown in drawings, said plurality of permanent magnets is meant the tile-shaped permanent magnet (9) that is with on the pipe (5) in nonferromagnetic, (21), (32), their pole arrangement can along device axially, also can be radially along device, as required, for reaching better magnetic treating result, be equipped with on the basis of tile-shaped permanent magnet, centre at this device can be equipped with nonferromagnetic inner sleeve (7), and the constant bar (6) that polarity is arranged vertically is housed in the inner sleeve.
