Abstract

Устройство, предназначенное для удержания давления в скважине, включает гидравлическую камеру плашек, поршень с плашками и нагнетательный поршень внутри корпуса. Поршень с плашками имеет концы, соединенные с плашкой и с гидравлической камерой плашек. Нагнетательный поршень имеет концы, соединенные с гидравлической камерой плашек и с источником гидравлической жидкости. Конец нагнетательного поршня, соединенный с источником гидравлической жидкости, имеет площадь поверхности, превышающую площадь поверхности конца, соединенного с гидравлической камерой плашек. Гидравлическая жидкость из источника гидравлической жидкости оказывает первое давление на второй конец нагнетательного поршня для перемещения нагнетательного поршня. Перемещение нагнетательного поршня оказывает второе давление, превышающее первое давление, на гидравлическую жидкость в гидравлической камере плашек для перемещения поршня с плашками и соединенной с ним плашки в закрытое положение.
