Abstract

"EQUIPAMENTO DE JUNçãO LATERAL PARA PROPORCIONAR UMA JUNçãO ENTRE UM FURO DE POçO PRINCIPAL E UM RAMAL LATERAL, MéTODO PARA PROPORCIONAR UMA MONTAGEM DE JUNçãO VEDADA PRóXIMA A UMA JUNçãO ENTRE UM FURO PRINCIPAL E UM FURO DE RAMAL LATERAL, MéTODO DE DESDOBRAMENTO DE UM DISPOSITIVO DE ACABAMENTO EM UM FURO DE RAMAL LATERAL E SISTEMA PARA USO EM UM POçO POSSUINDO UMA PLURALIDADE DE RAMAIS LATERAIS". Um equipamento e método de acabamento de poço, que compreende uma montagem de junção possuindo um gabarito e um conector de ramal lateral engajável com o gabarito para acoplar um furo principal a um furo de ramal lateral. Para melhorar as características de interengajamento do gabarito e conector, um arranjo da montagem de junção utiliza um mecanismo contínuo de interengajamento do trilho e o entalhe. Em um outro arranjo, uma parte do mecanismo de interengajamento do trilho e o entalhe é segmentada ao invés de ser contínua. Um método e equipamento são também proporcionados em alguns arranjos para possibilitar o posicionamento de dispositivos inteligentes de acabamento em um ramal lateral. Adicionalmente, algumas montagens de junção compreendem mecanismos de controle de fluxo para controlar a mistura ou não, dos fluidos provenientes de diferentes regiões no furo do poço.
