Abstract

"SISTEMA E MéTODO DE PRESSãO DE FUNDO DE POçO CONTROLADA ATIVA". A presente invenção refere-se a um sistema de perfuração de furo de poço que possui uma seção umbilical que porta uma sonda perfuratriz em um furo de poço. O fluido de perfuração bombeado para a seção umbilical descarrega no fundo de sonda perfuratriz e retorna através de um espaço anular entre a seção umbilical e o furo de poço, carregando detritos de perfuração aprisionados. Um dispositivo de diferencial de pressão ativa (dispositivo de APD), tal como uma bomba a jato, turbina ou bomba centrífuga, em comunicação com o fluido de retorno, produz um diferencial de pressão através do dispositivo, que altera a pressão abaixo ou no fundo de poço do dispositivo. O dispositivo de APD pode ser acionado por um motor de deslocamento positivo, uma turbina, um motor elétrico ou um motor hidráulico. Um controlador controla a operação do dispositivo de APD em resposta a instruções programadas e/ou um ou mais dos parâmetros de interesse detectados por um ou mais sensores. Um sistema preferido é um sistema de laço fechado que mantém o furo de poço em uma condição abaixo do equilíbrio, condição em equilíbrio ou condição além do equilíbrio.
