Abstract

The invention relates to an aluminum-silicon-tellurium-copper magnetic alloy, a preparation method and application thereof. The aluminum silicon tellurium copper magnetic alloy includes aluminum, silicon, copper, tellurium and magnetic metal elements. Taking the total mass of the aluminum-silicon-tellurium-copper magnetic alloy as 100%, the content of the aluminum is 45.6% to 51.2%, the content of the silicon is 33.5% to 37.5%, and the content of the copper is 9.8% to 19.5%, the content of tellurium is 0.12% to 0.48%, and the content of the magnetic metal element is 0.22% to 0.29%. The quantum ring prepared by the alloy has the function of effectively anti-dirt and / or anti-wax.

Description

technical field [0001] The invention relates to a tellurium-aluminum-silicon-copper magnetic alloy and a preparation method thereof, in particular to its application in one of anti-fouling and anti-wax. Background technique [0002] Waxing and scaling often occur in oilfield exploitation, resulting in the reduction of the cross-sectional area of ​​the oil flow channel and the failure of the piston pump, which brings serious troubles to the exploitation of oil. At present, the commonly used anti-scaling and anti-wax methods include mechanical method, physical method and chemical method. The mechanical method mainly adopts heat exchanger device, the physical method adopts sonic method, and the chemical method mainly uses chemical reagents. The effect is poor. [0003] In the field of water treatment, quantum rings made of high-silicon aluminum alloys purchased from Germany are widely used to prevent scaling in hard water, and good results have been seen. However, the quantum...
