Title
(PT) artigo de fundo de poço corrosível
Abstract
(PT)
a presente invenção refere-se a uma liga de magnésio adequada para uso como um artigo de fundo de poço corrosível. a liga de magnésio compreende: (a) 2 a 7%, em peso, de gd, (b) 0 a 2%, em peso, de y, (c) 0 a 5,0%, em peso, de nd, e (d) pelo menos 80%, em peso, de mg, e tem um alongamento conforme medido por astm b557m-10 de pelo menos 22%. a invenção também se refere a uma ferramenta de fundo de poço que compreende a liga de magnésio, um método para produzir uma liga de magnésio, e um método de faturamento hidráulico que compreende o uso de uma ferramenta de fundo de poço que compreende a liga de magnésio.
