Referring initially to
An expandable tubular member 18 that includes a lower tubular portion 18a, an upper tubular portion 18b, and an intermediate tapered tubular portion 18c is supported by the outer conical expansion surface 14b of the expansion cone 14. A shoe 20 that defines a valveable passage 20a is coupled to an end of the lower tubular portion 18a of the expandable tubular member 18. One or more compressible sealing members 22 are coupled to the exterior surface of the upper tubular portion 18b of the expandable tubular member 18.
In several exemplary embodiments, the outer expansion surface 14b of the expansion cone 14 may include conical, spherical, elliptical, and/or hyperbolic actuate segments that may or may not include faceted segments.
In an exemplary embodiment, during operation, the system 10 is initially positioned within a welbore 24 that traverses a subterranean formation 26. A fluidic material 30 may then be injected through the passages 12a, 14a, 20a, of the tubular support member 12, expansion cone 14, and shoe 20, respectively, in order to determine the proper functioning of the passages.
As illustrated in
In an exemplary embodiment, during the radial expansion and plastic deformation of the expandable tubular member 18, the vibrator 16 is operated to thereby generate vibratory energy. As a result, in an exemplary embodiment, the operational pressure of the injected fluid 28 required during the radial expansion of the tubular member 18 is reduced thereby increasing the operational efficiency of the system 10.
In an exemplary experimental test of the system 10, a comparison was made between the operation of the system, with and without the vibrator 16. The following table summarizes the comparative results of the exemplary experimental test of the system 10, with and without the vibrator 16:
Thus, in an exemplary experimental test of the system 10, with and without the vibrator 16, the use of the vibrator reduced the operating pressure of the injected fluid 28 during the radial expansion of the tubular member 18 by approximately 25%. This was an unexpectedly large reduction in the operating pressure of the injected fluid 28 provided by the operation of the vibrator 16. As illustrated in
Thus, in an exemplary experimental implementation of the system 10, the operation of the system with the vibrator 16 reduced the required operating pressure of the injected fluidic material 28 thereby enhancing the operational efficiency of the system and reducing the required radial expansion forces. Based upon the exemplary experimental results of the operation of the system 10, as well as theoretical analysis of the operation of the system, the reduction in the required expansion forces necessary to radially expand and plastically deform the tubular member 18 is due to at least one or more of the following phenomena: 1) the vibratory energy generated by the vibrator 16 reduces the contact and/or dynamic friction coefficient between the interior surface of the tubular member and the tapered exterior surface 14b of the expansion cone 14; and/or 2) the vibratory energy generated by the vibrator is absorbed by the tubular and thereby increases the plasticity and formability of the tubular member. Furthermore, an additional benefit of the system 10 with the vibrator 16 is that the need for a lubricating material between the interior surface of the tubular member and the tapered exterior surface 14b of the expansion cone 14 may be reduced.

In an exemplary embodiment, during operation, the system 100 is initially positioned within a welbore 24 that traverses a subterranean formation 26.

As illustrated in
In an exemplary embodiment, during the radial expansion and plastic deformation of the expandable tubular member 18, the vibrators 16 and/or 104 are operated to thereby generate vibratory energy. As a result, the required operational pressure of the injected fluid 28 may be reduced thereby increasing the operational efficiency of the system 100.
