Abstract

um aparelho inclui um estrangulamento de orifício variável disposto dentro de um riser. o riser é conectado entre uma plataforma de perfuração e um furo de poço. uma unidade de controle está em comunicação de sinal com o estrangulamento de orifício variável. a unidade de controle é operável para controlar uma área de fluxo do estrangulamento de orifício variável, de modo que uma pressão de fluido selecionada seja mantida no furo de poço.
