摘要： An oil rig system includes a rotary table, an elevator and an alignment subsystem. The rotary table is aligned with a wellhead opening and is centered on a first axis. The elevator includes flexible links. The alignment subsystem has a running tool and a knuckle joint. The running tool has a first end and a second end. The running tool is configured to attach to a packoff body. The knuckle joint is attached to the first end of the running tool and is attached to the elevator. The knuckle joint is configured to angularly deflect.

摘要： A wellhead assembly includes a production tree, a sacrificial fluid control assembly, an adaptor assembly, and a sleeve. The sacrificial fluid control assembly is fluidly coupled to the production tree. The adaptor assembly resides between the production tree and the sacrificial fluid control assembly. The adaptor assembly forms, with the adaptor assembly attached to the production tree and the sacrificial fluid control assembly, a common bore. The sleeve is disposed within the common bore and extends from the adaptor assembly to the tubing spool. The sleeve includes i) a first end that forms, with the adaptor or the sacrificial fluid control assembly, a first fluid seal, and ii) a second end opposite the first end and forming, with the tubing spool, a second fluid seal such that the sleeve fluidly isolates a first section of the common bore from a second section of the common bore.

摘要： An annulus seal system includes a retention plate mounted to a tubing in a wellbore at an uphole longitudinal end of the tubing and an annular isolation system coupled to the retention plate. The annular isolation system includes a bottom holding plate positioned in an annulus between two tubings, a seal element residing on the bottom holding plate to seal the annulus between the tubings, a torque plate, and a top holding plate. The seal element is positioned between the bottom holding plate and the torque plate, and the torque plate moves in a longitudinal direction toward the bottom holding plate to compress the seal element between the bottom holding plate and the torque plate. The top holding plate mounts to the retention plate, and includes an adjustment mechanism engaged with the torque plate to control movement of the torque plate in the longitudinal direction.
