Abstract

Se describen sistemas y métodos para elevar fluido de perforación de un pozo en un yacimiento submarino. Algunas modalidades de sistema incluyen una columna de perforación suspendida en un tubo vertical de perforación para formar el pozo, y una fuente de fluido de perforación para suministrar fluido de perforación a través de la columna de perforación durante la perforación. Un desviador está acoplado entre el tubo vertical de perforación y una línea de retorno, mientras que un tubo vertical de fuerza está acoplado a la línea de retorno en una interfase. Una fuente de fluido de elevación suministra fluido de elevación suministra fluido de elevación a través del tubo vertical de fuerza en la línea de retorno. El fluido de elevación es inyectado intermitentemente desde el tubo vertical de fuerza a través de la interfase en la línea de retorno para formar uno o más tarugos de fluido de elevación ubicados entre tarugos de fluido de perforación, de tal manera que la densidad combinada del fluido de elevación y el fluido de perforación en la línea de retorno es menor que la densidad del fluido de perforación solo.
