摘要： A lock assembly of a blowout preventer is provided. The blowout preventer includes a ram assembly slidably positionable in the channel and engageable with a tubular. The ram assembly includes a ram block, a ram cylinder, and a ram shaft 236. The lock assembly includes a lock cylinder 340 and a lock piston 342. The lock cylinder 340 is operatively connectable to the ram cylinder 238. The ram shaft 236 has an end slidably extendable into a lock cavity 352 of the lock cylinder 340. The lock piston 342 is slidably positionable in the lock cylinder 340 and separates the lock cavity 352 into a lock 344 and a closing chamber 346. The lock piston 342 has a ram surface engageable with the end when the lock piston 342 is in a locked position, and a ram hole 352 therethrough to receive the end when the lock piston342 is in an unlocked position whereby the ram block is selectively lockable about the tubular.

摘要： A locking door assembly, blowout preventer and method are provided. The blowout preventer is for sealing about a tubular extending from a wellbore of a wellsite. The blowout preventer includes a housing having a bore and a channel therethrough. The tubular is positionable through the bore and engageable therein. The blowout preventer also includes a door assembly including a door slidably positionable along an axis of the channel and providing selective access to the channel, and a lock. The lock includes at least one locking member having at least one raised portion extending along the door assembly in a direction transverse to the axis of the channel. The locking member is extendable into at least one corresponding receptacle of the housing and movable therealong between an unlocked and a locked position whereby the door assembly is selectively retractable from the housing.

摘要： A wellsite connector for connecting components of a wellsite is provided. The wellsite has a wellbore extending into a subsurface formation. The wellsite connector includes a connector body having an end adapted for coupling to a first of the components and a cavity to receive a second of the components, a piston axially movable in the connector body and having a piston profile along an inner surface thereof, and a plurality of collets. The collets are positionable about the connector body adjacent the piston and radially movable thereabout. The collets have a collet profile along an outer surface thereof corresponding to the piston profile of the piston. The collets also have a grip profile along an inner surface thereof selectively engageable with the second of the components whereby the collets are selectively latchable about the second of the components.
