Abstract

patente de invenção: "sistema e método para perfuração de um poço submarino". a presente invenção refere-se a uma bomba de lama submarina que pode ser utilizada para retornar fluido de perfuração pesado para a superfície. a fim de fornecer uma exigência menos rígida para tal bomba e para melhor gerenciar a preassão de fundo de poço no caso de um kick de gás ou evento de controle de poço, o gas deve ser separado do fluido de perfuração antes de o fluido de perfuração entrar na bomba de lama submarina e a pressão dentro da câmara de separação. a sucção da bomba de lama deve ser controlada e mantida igual ou inferior à pressão de água do mar ambiente. isso pode ser alcançado dentro das cavidades do bop submarino por uma disposição de sistema e métodos explicados. essa função pode ser utilizada com ou sem um elevador de perfuração conectando o bop submarino a uma unidade de perfuração acima do corpo de água.
