Rare earth high-efficiency strong magnetic anti-scaling device

Abstract

The invention relates to a rare earth high-efficiency strong-magnetism anti-scaling device which comprises a coupler, a rare earth strong-magnetism array and a pressurizer which are connected in series through a hollow pipe. The coupler is used for assembling the rare earth high-efficiency strong-magnetism anti-scaling device on the pipe in front of a pump body. The rare earth strong-magnetism array comprises a plurality of groups of rare earth strong magnets which are evenly arranged around the pipe, each group of rare earth strong magnets comprise an even number of arc magnets evenly arranged around the outer peripheral face of the pipe, the magnetic poles are pointed at the arc circle center, and a strong magnetic field is formed on the cross section of the pipe. A plurality of flow guide holes not arranged on the same plane as the pipe central axis are formed on the pressurizer, and the flower guide holes are sequentially inclined through a certain angle towards the same direction around the pipe central axis. Fluid output from the pressurizer enters the pipe provided with the rare earth strong-magnetism array in a multi-strand spiral rising mode to be magnetized by the formed strong magnetic field, and physical property change of the fluid occurs accordingly.

Description

technical field [0001] The invention relates to the technical field of crude oil development and gathering and transportation, in particular to a rare earth high-efficiency strong magnetic antiscaling device used in oil and gas field development and gathering and transportation projects. Background technique [0002] During the development of oil and gas fields, the fluids (oil, gas, water) in the oil and gas reservoirs flow out of the oil and gas layers. Due to the changes in temperature, pressure and oil, gas and water balance, they are easy to flow in underground reservoirs, oil production wells, casings, production The deposition of inorganic salts in the tubing will generate scale, and the occurrence of scaling will block the oilfield pipeline, which will have a negative impact on production, reduce production capacity, increase energy consumption, make normal continuous operation impossible, and even stop production. [0003] For example, the comprehensive water conten...

Problems solved by technology

[0005] However, the increase of the liquid flow rate will shorten the time for the liquid to flow through the magnetic field, weaken the magnetization time of the liquid in the magnetic field, and make it difficult to combine the two methods of the magnetic field and the pressurizer in the prior art.
