Abstract

The invention discloses a nano-particle reinforced alloy material with an antiscaling function. The nano-particle reinforced alloy material with the antiscaling function comprises the following components in percentage by mass: 45-75% of Cu, 15-30% of Zn, 6.0-22% of Ni, 2.0-10% of Sn, 1.0-15% of Pb and 0.1-1.0% of Al2O3, wherein the sum of the percents by mass of said various components is 100%. The invention further discloses a preparation method of the ano-particle reinforced alloy material with the antiscaling function. The preparation method comprises the following steps: melting the various raw materials to form a uniform melt, pouring the uniform melt in a stainless steel ingot mould, carrying out rotary electromagnetic stirring for 30-40 seconds after pouring for 5-8 seconds, cooling, crusting to form a metal ingot, and watering to cool and form. The nano-particle reinforced alloy material has a hardness of 180-220HV, a uniform isometric crystal structure, a grain size of 7-8, and an underwater alloy scale-inhibition rate of 75-85%, and can be used for metal scale inhibition for oilfield pipelines.

Description

technical field [0001] The invention relates to alloy materials, in particular to a nano particle-reinforced alloy material with an anti-fouling function, and belongs to the technical field of alloys. Background technique [0002] At present, the oil and water wells in the oil field all have scaling phenomena. The scale samples are mainly calcium, magnesium, barium, and strontium scale salts through analysis and testing. Treatment measures commonly used in oil fields include chemical anti-scaling, physical anti-scaling and metal anti-scaling. The chemical anti-scaling process pollutes the environment and has the disadvantages of short anti-scaling period and high cost. Physical anti-scaling is rarely used and the anti-scaling effect is not obvious. At present, there are no mature products for metal anti-scaling in China. The imported metal anti-scaling materials are single, and the adaptability to the specific well conditions of the oil field is not strong. For example, the...
