Abstract

Устройства регулирования противодавления, применяемые для регулирования давления текучей среды в стволе скважины, требуют различных средств для работы, таких как устройство подачи воздуха. Устройство, раскрытое в данном документе, обеспечивает продолжительную работу одного или нескольких устройств управления противодавлением, когда действие средств обеспечения работы устройств управления противодавлением намеренно или непреднамеренно прерывается.
