Soluble magnesium alloy, preparation method and application thereof and fracturing product

The invention relates to a soluble magnesium alloy, a preparation method and application thereof and a fracturing product, and the soluble magnesium alloy comprises the following components in percentage by mass: 8%-12% of Gd, 2.4%-3.5% of Y, 0.08%-1% of Zr, 0.2%-4.5% of Ni, 0.3%-2.5% of doping elements, 0.01%-0.05% of Fe, 0.01%-0.055% of Cu and the balance of Mg. Wherein the doping element is selected from at least one of La, Ce, Eu and Yb. The soluble magnesium alloy has excellent solubility, is high in dissolving speed in electrolyte such as KCl and the like, can keep high compression strength and high dissolving speed even after heat treatment, and is beneficial to improving the exploitation efficiency when being used for preparing fracturing products for exploiting oil and gas. 本发明涉及一种可溶镁合金及其制备方法与应用、压裂制品，按照质量百分数计，所述可溶镁合金由以下组分组成：8％～12％Gd、2.4％～3.5％Y、0.08％～1％Zr、0.2％～4.5％Ni、0.3％～2.5％掺杂元素、0.01％～0.05％Fe、0.01％～0.055％Cu及余量Mg；其中，所述掺杂元素选自La、Ce、Eu和Yb中的至少一种。该可溶镁合金具有优异的可溶性，在KCl等电解液中溶解速度快，即使是在热处理后，镁合金也还能保持高压缩强度和快速溶解速率
