Rapidly degradable magnesium alloy material as well as manufacturing method and application thereof

Abstract

The invention discloses a rapidly degradable magnesium alloy material. The material comprises the following components: elements such as Al, Li, Ca, Y, Si, Ni, Cu and Fe. The invention also discloses a preparation method and the application of the rapidly degradable magnesium alloy material. Compared with the prior art, the rapidly degradable magnesium alloy material has the advantages that the problems of failure in resisting high temperatures and failure in meeting high-temperature and high-bearing operation requirements of the existing easily degradable materials or easily degradable magnesium alloy materials and products thereof are solved, meanwhile, the material is controllable in density, the slag or the corrosion product of the material meets the requirements of flowback operations, and multiple technical effects of simplicity and high efficiency, low cost, energy conservation, environmental protection and the like can be achieved.

Description

technical field [0001] The present invention relates to a kind of magnesium alloy material, and this magnesium alloy material is made into products (such as soluble ball, soluble target, soluble ball seat, soluble bridge plug etc.) degradation. The invention also relates to the preparation method and specific application of the magnesium alloy material, belonging to the field of magnesium alloy technology Background technique [0002] Petroleum oil fields or oil production wells with low and medium osmotic pressures have low natural production capacity due to low downhole osmotic pressure, and oil oil fields or oil production wells with high osmotic pressures have reduced osmotic pressure and narrow or blocked oil outlet channels in the later stage of oil production. As a result, the efficiency of oil extraction is low, the output is low, and even no oil is produced, forcing oil production companies to adopt various advanced, high-tech and methods to improve extraction effi...

AI Technical Summary

Problems solved by technology

Obviously, these materials or alloys and their products are both dense and harmful, and are not suitable or cannot meet the requirements of high-temperature operations, nor are they suitable for the progress and development of modern oil recovery technology.

[0007] On this basis, the applicant has made improvements, see the application number 201410246482.7 of the Chinese invention patent application publication "Easily Soluble Magnesium Alloy Material and Its Manufacturing Method and Application" (application publication number is CN104004950A), the material includes the following components Al , Li, Ca, Zn, In, Ga, Si, Zr and other elements, since the alloy does not contain gallium, lead, mercury, thallium poisonous or environmentally harmful elements, it also solves the problem of the harmfulness of the alloy, but the alloy density The control is not strict, and it is easy to cause the problem of excessive density. At the same time, the alloy contains a variety of low melting point metals (such as In, Ga, Zn, Li, etc.), resulting in poor heat resistance. The compressive strength at room temperature is 300MPa Around, at high temperature such as 130 ℃ ~ 170 ℃, the compressive strength is low
