Abstract

Устройства контроля стабильного противодавления применяют для регулирования давления текучей среды в стволе скважины для обеспечения постоянного давления в скважине. Противодавление можно устанавливать из соотношения между скоростью работы бурового насоса и давления, создаваемого насосом. Программы бурения, раскрытые в данном документе, обеспечивают продолжительную работу одного или нескольких устройств управления противодавлением для обеспечения постоянного давления на забое, когда выполняются соединения обсадной колонны.
