Abstract

SISTEMAS E MÉTODOS PARA O GERENCIAMENTO DE PRESSÃO EM UM FURO DE POÇO. Trata-se de um método para perfurar um poço submarino a partir de uma sonda através de uma cabeça de poço submarino abaixo da sonda que inclui empregar um sistema de perfuração de gradiente único ou duplo que inclui uma coluna de perfuração que se estende a partir da sonda para o poço e bombas de lama de superfície para bombear o fluido de perfuração através da coluna de perfuração e para um espaço anular do poço do poço. O sistema de perfuração inclui um dispositivo de rotação submarino para conduzir o fluido de perfuração a partir do espaço anular do poço e através de um uma unidade de processamento de sólidos. Em seguida, uma bomba submarina conduz o fluido de perfuração da unidade de processamento de sólidos para uma linha de retorno de volta para a sonda. A bomba de lama de superfície e a bomba submarina são dispostas em estágios em coordenação para reter pressão e/ou remover pressão no espaço anular do poço para manter um gradiente de pressão selecionado no espaço anular do poço.
