Abstract

Противовыбросовый превентор (100), предназначенный для гидравлической герметизации скважины, включает в себя кожух (102), предназначенный для размещения над устьем скважины и для окружения бурильной колонны (112), множество плашек (120), расположенных перпендикулярно оси (114) бурильной колонны и предназначенных для взаимодействия с бурильной колонной (114) и для гидравлической изоляции кольцевого зазора (116) между скважиной и бурильной колонной (112), когда плашки находятся в закрытом положении, и роликовый запор (350, 250) вокруг штока (326, 226, 126) каждой плашки (120), предназначенный для удержания плашки (120) в закрытом положении.A blowout preventer (100) designed for hydraulic sealing of a well includes a casing (102) designed to be placed above the wellhead and to surround the drill string (112), a set of dies (120) located perpendicular to the axis (114) of the drill string intended for interaction with the drill string (114) and for hydraulic isolation of the annular gap (116) between the well and the drill string (112) when the dies are in the closed position, and the roller lock (350, 250) around the stem (326, 226, 126 a) each pl shki (120) for holding dies (120) in the closed position.
