Abstract
Present embodiments are directed to a device for a top drive drilling system. The device includes a movable sleeve configured to be disposed around at least a portion of a sub. The movable sleeve is configured to be selectively disposed around a tubular by sliding axially along the sub. The device also includes a plurality of engagement features extending inwardly from an inner circumference of the movable sleeve. When the movable sleeve is disposed around the tubular, the plurality of engagement features are configured to engage the tubular when the movable sleeve is rotated in a first direction and to not engage the tubular when the movable sleeve is rotated in a second direction.
Claims18
A device for a top drive drilling system comprising:
- a sub having a first coupling end configured to mate with the top drive drilling system and a second coupling end configured to mate with a tubular;
- a movable sleeve disposed around at least a portion of the sub, the movable sleeve configured to be selectively disposed around the tubular by sliding axially along the sub;
- a sealing device disposed between the movable sleeve and the sub;
- and
- a plurality of engagement features extending inwardly from an inner circumference of the movable sleeve, wherein, when the movable sleeve is disposed around the tubular, the plurality of engagement features are configured to engage the tubular when the movable sleeve is rotated in a first direction and to not engage the tubular when the movable sleeve is rotated in a second direction.
A device for a top drive drilling system comprising:
- a movable sleeve configured to be disposed around at least a portion of a sub, the movable sleeve configured to be selectively disposed around a tubular by sliding axially along the sub;
- a sealing device configured to provide a seal between the movable sleeve and the tubular, when the movable sleeve is disposed around the tubular;
- and
- a plurality of engagement features extending inwardly from an inner circumference of the movable sleeve, wherein, when the movable sleeve is disposed around the tubular, the plurality of engagement features are configured to engage the tubular when the movable sleeve is rotated in a first direction and to not engage the tubular when the movable sleeve is rotated in a second direction.
A method for coordinating tubulars in a top drive drilling system comprising:
- sliding a movable sleeve axially along a sub and forming a seal between the movable sleeve and the sub via a sealing device;
- disposing a plurality of engagement features around a tubular, wherein the plurality of engagement features extend inwardly from an inner circumference of the movable sleeve;
- rotating the plurality of engagement features around the tubular in a first direction;
- and
- engaging the plurality of engagement features with the tubular to cause the plurality of engagement features to apply a frictional force to the tubular, wherein the frictional force is configured to cause the tubular to rotate in the first direction.
