Abstract

apoio de pinça de pétala retrátil para uma vedação subterrãnea. a presente invenção refere-se a um tampão de alta expansão que tem múltiplos elementos de vedação e um sistema de barreira de extrusão que usa pétalas em sobreposição em uma pilha de anéis. ao ajustar o tampão, as pétalas são movidas de modo elástico em direção a uma parede tubular circundante em uma deformação elástica entre um compartimento que circunda o mandril e um anel afunilado no mandril. o ato de intercalar controla a quantidade de deformação e permite que uma força de energia potencial seja armazenada nas pétalas, o que permite que elas retornem em direção à sua posição inicial conjunto de tampão é liberado e as vedações são permitiras relaxar e se estender de maneira axial à medida quelas encolhem de forma radial. o tampão pode, em seguida, ser removido sem a moagem. as expansões na ordem de 25% da dimensão de vedação inicial são contempladas.
