Abstract

montagem de anel antiextrusão de obstruidor de furo de poço, obstruidor e método. uma montagem de anel antiextrusão para um obstruidor de furo de poço que age como um limitador de extrusão para u m elemento de vedação e encaixada com o furo de poço, também operando como um deslizamento para ancorar o obstruidor no lugar. um obstruidor de furo de poço inclui uma estrutura única que age tanto para retroceder a extrusão do elemento de vedação quanto para encaixar com a parede de furo de poço. por exemplo, a estrutura é um anel antiextrusão que inclui uma estrutura de agarramento na sua superfície de contactar parede externa. o obstruidor de furo de poço inclui: um madril, um elemento de vedação deformável circundando o mandril e adaptado para ser expandido radialmente para fora do mandril, o elemento de vedação deformável incluindo uma extremidade; um anel antiextrusão circundando o mandril e posicionado adjacente à extremidade do elemento de vedação deformável, o anel antiextrusão tendo uma superfície anular voltada para o interior e uma superfície anular voltada para o exterior definindo um diâmetro externo através do anel antiextrusão, o anel antiextrusão sendo expansível para aumentar o diâmetro externo para expandir para fora do mandril ao lado do elemento de vedação deformável e a superfície anular voltada para o exterior incluindo uma estrutura de agarramento para agarrar em uma superfície de restrição em um poço.
