Abstract

resumo “conjunto de vedação, conjunto de cabeça de poço e método de vedação” trata-se de uma vedação anular (22, 22a) para uso em um conjunto de cabeça de poço (10) que tem pernas interior (28) e exterior (30), sendo que cada uma se estende em uma direção que é geralmente paralela com um eixo geométrico da vedação para definir um espaço anular no espaço entre os mesmos. endentações (34, 38) são fornecidas em uma superfície exterior da vedação, de modo que quando a vedação está energizada e as pernas são estimuladas radialmente separadas uma da outra, as endentações se engatem a uma superfície de contato de um tudo de fundo de poço. integrar as endentações no tubular cria uma barreira de fluxo através da interface entre a vedação e o tubular. as endentações deformam a superfície do tubular, o que cria uma força de travamento que se opõe ao movimento do eixo geométrico relativo do tubular.
