Abstract
In at least one embodiment, a system for a slip hanger or packoff to be used with oilfield equipment is disclosed. The system includes an arrangement of one or more load relief plates to be above or below one or more profiled plates, the one or more profiled plates having a profile that induces a change in shape in the one or more load relief plates under a load applied to the slip hanger or the packoff.
Claims20
A system for a slip hanger or a packoff to be used with oilfield equipment, comprising:
- an arrangement, comprising:
- one or more load relief plates to be above or below one or more profiled plates, the one or more profiled plates comprising a profile of indentations that are circumferentially provided in the one or more profiled plates and that induces a change in shape, in a vertical orientation which is along a wellbore, in the one or more load relief plates under a load applied from a thermal change to the slip hanger or the packoff, wherein a first profiled plate of the one or more profiled plates comprises one or more screw holes;
- and
- one or more screws provided in the one or more screw holes, the one or more screws arranged parallel to the vertical orientation and the one or more screws extending through at least the first profiled plate and a first load relief plate of the one or more load relief plates.
A slip hanger or packoff system, comprising:
- a plate arrangement, wherein the plate arrangement comprises:
- a profiled plate having a profile that comprises circumferentially-spaced indentations;
- an upper plate configured to be disposed above the profiled plate;
- and
- a lower plate configured to be disposed below the profiled plate;
- and
- a plurality of screws configured to be secured through vertical screw holes in the upper plate, the profiled plate, and the lower plate such that, while under load, the plate arrangement vertically deforms at the circumferentially-spaced indentations on the profiled plate to facilitate accounting for thermal change in the slip hanger or packoff system.
A method of implementing a slip hanger or packoff system, comprising:
- securing a plurality of screws vertically through screw holes in a plate arrangement such that an upper plate is secured above a profiled plate and a lower plate is secured below the profiled plate, wherein the profiled plate has a profile that comprises circumferentially-spaced indentations;
- and
- applying load to vertically deform the plate arrangement at the circumferentially spaced indentations in the profiled plate to facilitate accounting for thermal change in the slip hanger or packoff system.
