Abrégé français

Un dispositif de prise à griffes pour ancre de tubulure destiné à ancrer un équipement de puits dans un conduit de puits pour arrêter le mouvement à la fois dans les sens longitudinales et rotationnels. Un mandrin relié à léquipement présente une ou plusieurs rainures pour recevoir de manière coulissante des tiges dentraînement respectives depuis un corps de traînée sur le mandrin. Une cage de coin de retenue sur le mandrin contient un ou des coins de retenue pour se mettre en prise et hors prise sélectivement avec le conduit. La manipulation du mandrin à la surface fait en sorte que les tiges dentraînement se déplacent dans la ou les rainures du mandrin et que la surface conique du corps de traînée se dirige vers la cage de coin de retenue en entraînant le ou les coins de retenue vers lextérieur pour saisir le conduit. Le fait de tirer davantage à la surface maintient la position fixée. Lancre est libérée à la surface en relâchant la tension, en faisant tourner le mandrin dans le second sens et en tirant sur le mandrin pour dégager le ou les coins de retenue.


Abrégé anglais


A tubing anchor catcher for anchoring well equipment in a well conduit to
arrest
movement in both longitudinal directions and rotational directions. A mandrel
connected to the equipment has one or more grooves for slideably receiving
respective
drive pins from a drag body on the mandrel. A slip cage on the mandrel houses
a slip or
slips for selectively engaging and disengaging the conduit. Manipulation of
the mandrel
at surface causes the drive pins to move within the one or more grooves on the
mandrel
and the drag body conical surface to move toward the slip cage driving the
slip or slips
outward to grip the conduit. Further pulling at surface maintains the set
position. The
anchor is unset at surface by releasing the tension, rotating the mandrel in
the second
direction, and pulling the mandrel to disengage the slip or slips.

tubing string, the mandrel comprising at least one externally facing
groove;
a slip cage that is slidably mountable about the mandrel, the slip cage
comprising a slip or slips that are adapted for engaging the inner surface
of the well conduit;
a first upper cone element that is slidably mountable about the mandrel,

element comprising a first conical surface;
iv. a drag body that is slidably mountable about the mandrel, adjacent the
slip cage towards a second end of the tool, the drag body comprising at
least one drag member for frictionally engaging an inner surface of the
well conduit, at least one drive pin for engaging the externally facing
groove, and a second conical surface; and
v. a compressible biasing member that is slidably mountable about the
mandrel adjacent the first cone element for engaging the first cone
element in a compressed state;
wherein the tool is articulatable between a run-in position, in which the
slip or slips are retracted into the slip cage and a set position, in which
17

the first and second conical surfaces are moved underneath the slip or
slips for extending the slip or slips outward from the slip cage and
wherein the at least one drive pin controls movement of the mandrel
between the run-in and set positions.
2. The tool of claim 1, wherein the at least one externally facing groove
comprises a
C-shape with a first arm and a second arm that are connected by a central
portion.
3. The tool of claim 2, wherein in the run-in position, the at least one
drive pin is
positioned within a shoulder of the second arm of the at least one externally
facing groove.
4. The tool of claim 3, wherein in the set position, the at least one drive
pin is
positioned within a first shoulder of the first arm of the at least one
externally
facing groove and the drag body is closer to the biasing member than in the
run-
in position.
5. The tool of claim 4, wherein the tool is moveable to a pre-set position,
wherein
the at least one drive pin is positioned within a second shoulder of the first
arm
of the at least one externally facing groove, the second shoulder of the first
arm
is opposite to the first shoulder of the first arm.
6. The tool of claim 5, wherein the at least one drive pin is positionable
from the
run-in position to the pre-set position by means of a longitudinal movement of

the mandrel in a first direction relative to the drag body, then movement in
an
opposite second direction together with a quarter turn relative to the drag
body;
18

and wherein the at least one drive pin is positionable from the pre-set
position
to the set position by movement of the mandrel in the first direction.
7. The tool of claim 1, wherein in the set position, the first cone element
is movable
under the slip or slips due to the biasing member being compressed.
8. The tool of claim 1, wherein the at least one drive pin is shearable for
providing a
secondary release mechanism.
9. The tool of claim 1, further comprising a second cone element that is
mountable
about the mandrel between the drag body and the slip cage, wherein the second
cone element defines the second conical surface.
10. The tool of claim 9, wherein the second cone element is connectible to
the drag
body by one or more shear pins, wherein the one or more shear pins are
shearable at a lower shear force than the at least one drive pin and the one
or
more shear pins provide a secondary release mechanism.
11. The tool of claim 1, wherein the slip or slips each comprise upward
gripping
teeth and downward gripping teeth.
12. The tool of claim 1, wherein the drag body further comprises one or
more cap
screws that extend outwardly from the drag body, each through an associated
slot that is defined by the slip cage, wherein the one or more cap screws and
the
associated slots prevent the drag body and slip cage from longitudinally
separating.
13. The tool of claim 1, wherein the slip or slips comprise three or four
slips.
19

14. The tool of claim 13, wherein in the set position, the three or four
slips define
by-pass spaces there between.
15. The tool of claim 13, wherein each of the one or more cap screws and
the
associated slots are positioned between the three or four slips.
16. The tool of claim 1, wherein the mandrel comprises three or four
externally
facing grooves that are associated with three or four drive pins of the drag
body.
17. The tool of claim 1, wherein the externally facing grooves and the
drive pins are
generally evenly radially spaced about the tool.
18. A method for anchoring well equipment or tubing in a well conduit for
maintaining tension, said method comprising the steps of:
i. providing a tubing anchor catcher comprising:
a) a mandrel that is connectible at a first end and a second
end within the tubing string, the mandrel comprising at
