Abstract

par de lâminas de cisalhamento, preventor de erupções (bop) e bop de tipo gaveta de cisalhamento. trata-se de um par de lâminas de cisalhamento e um preventor que tem o par de lâminas de cisalhamento. as lâminas de cisalhamento são configuradas para cortar um tubular dentro do preventor. as lâminas de cisalhamento têm diferentes geometrias das superfícies cortantes frontais. uma geometria promove um posicionamento seguro do tubular em relação à primeira lâmina enquanto a segunda geometria promove uma perfuração do tubular pela segunda lâmina.
