Abstract
In at least one embodiment, a slip hanger or a packoff to be used with oilfield equipment is disclosed as having slip segments to be supported by a slip bowl and to be associated with pins that have a self-retractive attribute. The self-retractive attribute is to allow engagement of the slip segments with a housing of the oilfield equipment based in part on a first direction of movement of the plurality of slip segments and is to allow an interface with individual ones of the plurality of slip segments in a second direction of movement for the plurality of slip segments.
Claims20
A system for a slip hanger or a packoff to be used with oilfield equipment, comprising:
- a plurality of slip segments supported by a slip bowl and associated with a plurality of pins having a self-retractive attribute, wherein the self-retractive attribute is configured to allow engagement of the plurality of slip segments with a housing of the oilfield equipment based in part on a first direction of movement of the plurality of slip segments, wherein the housing surrounds, at least partially, the slip bowl, wherein the self-retractive attribute is provided, at least in part, by an angled profile for individual ones of the plurality of pins, wherein the angled profile is to interface with a corresponding angled profile of individual ones of the plurality of slip segments, and wherein a second direction of movement of the plurality of slip segments allows disengagement of the plurality of pins from the housing by the self-retractive attribute and allows retraction of the plurality of pins into the slip bowl by the self-retractive attribute.
A method for a slip hanger or a packoff to be used with oilfield equipment, comprising:
- providing a plurality of slip segments to be supported by a slip bowl;
- providing a plurality of pins having a self-retractive attribute to be associated with the plurality of slip segments and with the slip bowl;
- and
- allowing, by at least in part the self-retractive attribute, engagement of the plurality of slip segments with a housing of the oilfield equipment based in part on a first direction of movement of the plurality of slip segments, wherein the housing surrounds, at least partially, the slip bowl, wherein the self-retractive attribute is provided, at least in part, by an angled profile for individual ones of the plurality of pins, wherein the angled profile is to interface with a corresponding angled profile of individual ones of the plurality of slip segments, and wherein a second direction of movement of the plurality of slip segments allows disengagement of the plurality of pins from the housing and allows retraction of the plurality of pins into the slip bowl by the self-retractive attribute.
