CORRODIBLE DOWNHOLE ARTICLE

摘要

This invention relates to magnesium alloys suitable for use as corrodible downhole articles, wherein the alloys have a corrosion rate of at least 50mg/cm 2 /day in 15% KCl at 93°C and a 0.2% proof strength of at least 50MPa when tested using standard tensile test method ASTM B557-10. The invention also relates to methods for producing the alloys, downhole tools comprising the alloys and methods of hydraulic fracturing using the downhole tools.
