Abstract

Предложены способ подводного бурения и система для управления давлением буровой текучей среды, в которых бурильную текучую среду закачивают вниз в ствол скважины через буровую колонну и возвращают обратно через кольцевое пространство между буровой колонной и стволом скважины. Давление буровой текучей среды контролируют путем выведения буровой текучей среды из водоотделяющей колонны (8) или противовыбросового превентора (6) на уровне между дном моря и поверхностью моря для обеспечения регулирования гидростатического напора буровой текучей среды. Выведенную буровую текучую среду и газ разделяют в подводном сепараторе (28), при этом газ выпускают к поверхности через выпускную линию (39), а текучую среду нагнетают к поверхности с помощью насоса (40).
