Abstract
An actuation tool includes a mandrel; at least one protrusion in the mandrel representing a deformation of the material of the mandrel resulting in the mandrel having a lesser axial dimension than it does with the protrusion removed or diminished; and a fluid inlet positioned to facilitate application of pressure to one of an inside or outside surface of the mandrel and method.
Description
- In the hydrocarbon recovery arts, actuation tools are a familiar component of most wellbore operations. Many different wellbore tools require setting once they are appropriately positioned in the downhole environment. Some examples include packers and bridge plugs although it will be recognized by those of skill in the art that many other devices also require setting. In many cases, the setting operation of such devices requires an axial motion. While hydraulic pressure derived from hydrostatic well pressure or from a pressure increasing action may be sufficient for some devices, others, because of their particular construction, are not settable based upon direct application of hydraulic pressure and instead require alternate actuation.
- Since there are a large number of different types of tools and a large number of types of actuation, the art is always in search of alternative actuation tool configurations.
- An actuation tool includes a mandrel; at least one protrusion in the mandrel representing a deformation of the material of the mandrel resulting in the mandrel having a lesser axial dimension than it does with the protrusion removed or diminished; and a fluid inlet positioned to facilitate application of pressure to one of an inside or outside surface of the mandrel.
- A method for applying a linear force includes applying pressure to the tool described immediately above, undeforming the at least one protrusion and causing extension of the mandrel due to the undeforming.
- Referring now to the drawings wherein like elements are numbered alike in the several Figures:
-
FIG. 1 is a schematic cross-sectional illustration of an actuation tool in accordance with the teaching hereof; and -
FIG. 2 is an illustration of the tool depicted inFIG. 1 in the stroked condition. - Referring to
FIG. 1 , a schematic illustration of an embodiment of anactuation tool 10 is shown in a non-actuated position. Thetool 10 includes amandrel 12 having a number of deformedportions 14. There may be one or moredeformed portions 14 as desired. The greater the number of deformedportions 14, the greater the length change in themandrel 12 upon actuation of the tool. Oneend 16 ofmandrel 12 is open for fluid communication throughinlet 38 to aninside volume 38 defined bymandrel 12, while anopposite end 18 is closed. Assuch mandrel 12 is receptive to hydraulic fluid at the volume defined thereby and responsive to an increase in pressure of that fluid to undeform any deformed portions of themandrel 12. Upon undeformation, one will appreciate that thefrustoconical segments 20 at eachdeformed portion 14 become more axially aligned with themandrel 12 and thereby cause growth in the axial length thereof. The appearance of thetool 10 will be as illustrated inFIG. 2 after undeformation. - Each
deformed portion 14 is formed by a circumferential radially inward collapse of the material ofmandrel 12 to form insidedimensions 22 ofportions 14 that are smaller than aninside dimension 24 of anundeformed portion 26 ofmandrel 12. In some configurations, the difference in inside dimension(s) 22 to inside dimension(s) 24 is substantial while in other configurations, it may be less. Moreover, it should be noted that indifferent portions 14 in thesame mandrel 12, theinside dimensions 22 may be different in order to create a staged actuation. This is possible because depending both upon the axial length of adeformed portion 14 and the amount of deformation of thatportion 14, the angle presented by thefrustocones 20 is varied. The greater the angle, the higher the hydraulic pressure required to undeform the portion (and the greater the length change). Where different configurations of theportions 14 are included in the same tool, then, the tool will extend more slowly as individual portions undeform in a sequence governed by their individual angular structure. - Alternatively, to the forgoing explanation of sequenced elongation of the
mandrel 12, it is also possible to create such sequencing by varying the thickness of the material at individual deformedportions 14. In this alternative, the thinner material sections will undeform first followed sequentially by the next successively thicker section. It will also be appreciated that angularity and material thickness can also be used together in some embodiments. - Facilitating creation of the deformed portions, in one embodiment, is a plurality of lines of weakness in the material of the mandrel. These lines of weakness are substantially circumferential and may represent a complete circumference or a broken circumference as desired. The lines of weakness in one configuration may be grooves in the material of
mandrel 12 located atnumerals numerals mandrel 12 but also indicate which surface ofmandrel 12 is grooved. The grooves in one embodiment are positioned such that when the deformation of thedeformed position 14 is effected, the grooves close. - While preferred embodiments have been shown and described, modifications and substitutions may be made thereto without departing from the spirit and scope of the invention. Accordingly, it is to be understood that the present invention has been described by way of illustrations and not limitation.
