An isolation valve is a device that provides isolation to a reservoir. A traditional application of an isolation valve is to protect the reservoir from damaging fluid during transition from completion to production. An isolation valve may include at least a trigger section and an actuator to remotely change the state of the isolation valve.
A system according to one or more embodiments of the present disclosure includes a housing assembly; a core rod disposed in the housing assembly, the core rod including an internal profile and an external profile; a power spring in cooperation with the core rod within the housing assembly, the power spring connected to a power spring stopper that is fixed to the housing assembly with at least one shear screw; an inner axial cycling piston bar including an external profile for mating engagement with the internal profile of the core rod; and a piston including a piston head, the piston being in cooperation with a cycling spring, and the piston being connected at an end of the inner axial cycling piston bar. In one or more embodiments of the present disclosure, the piston is configured to move in an upward direction as the cycling spring exerts a downward force on the piston head of the piston upon application of a cycling force in the upward direction. In one or more embodiments of the present disclosure, the piston head is configured to move in a downward direction as the downward force exerted by the cycling spring exceeds the upwardly applied cycling force, and the inner axial cycling piston bar connected to the piston is configured to move in the downward direction upon relaxation of the cycling force. According to one or more embodiments of the present disclosure, movement of the inner axial cycling piston bar in the downward direction also moves the external profile of the inner axial cycling piston bar in the downward direction, thereby causing the core rod to move an incremental distance in the downward direction, which compresses the power spring by the incremental distance.
A method according to one or more embodiments of the present disclosure includes applying a cycling force to a piston in an upward direction, wherein the piston includes a piston head and is in cooperation with a cycling spring, and wherein the applying step causes the piston to move in the upward direction as the cycling spring exerts a downward force on the piston head of the piston. In one or more embodiments of the present disclosure, the method further includes relaxing the cycling force, causing the piston head to move in a downward direction as the downward force exerted by the cycling spring exceeds the upwardly applied cycling force, and an inner axial cycling piston bar connected to the piston to move in the downward direction. According to one or more embodiments of the present disclosure, the inner axial cycling piston bar includes an external profile for mating engagement with an internal profile of a core rod disposed in a housing assembly, and wherein as the inner axial cycling piston bar moves in the downward direction, the external profile of the inner axial cycling piston bar moves an incremental distance in the downward direction, thereby causing the core rod to move the incremental distance in the downward direction. The method according to one or more embodiments of the present disclosure further includes compressing a power spring in cooperation with the core rod within the housing assembly by the incremental distance, the power spring being connected to a power spring stopper that is fixed to the housing assembly with at least one shear screw; moving the inner axial cycling piston bar and the external profile of the inner axial cycling piston bar in the upward direction when the cycling force changes to the upward direction, thereby causing the external profile of the inner axial cycling piston bar to collapse, disengage from the internal profile of the core rod, and skip to re-engage the internal profile of the core rod at a location measuring the incremental distance away; preventing the core rod from moving in the upward direction; repeating the applying, compressing, moving, and preventing steps until a compression force of the power spring causes the at least one shear screw to shear, thereby releasing the power spring stopper; and pushing the power spring stopper in the downward direction to actuate a hydraulic valve from a first position to a second position
However, many modifications are possible without materially departing from the teachings of this disclosure. Accordingly, such modifications are intended to be included within the scope of this disclosure as defined in the claims.
Certain embodiments of the disclosure will hereafter be described with reference to the accompanying drawings, wherein like reference numerals denote like elements. It should be understood, however, that the accompanying figures illustrate the various implementations described herein and are not meant to limit the scope of various technologies described herein, and:
In the following description, numerous details are set forth to provide an understanding of some embodiments of the present disclosure. However, it will be understood by those of ordinary skill in the art that the system and/or methodology may be practiced without these details and that numerous variations or modifications from the described embodiments may be possible.
In the specification and appended claims: the terms “up” and “down,” “upper” and “lower,” “upwardly” and “downwardly,” “upstream” and “downstream,” “uphole” and “downhole,” “above” and “below,” “top” and “bottom,” and other like terms indicating relative positions above or below a given point or element are used in this description to more clearly describe some embodiments of the disclosure.
The present disclosure generally relates to a system and method for actuating a hydraulic valve. More specifically, the present disclosure relates to a hydraulic trigger and an associated method for actuating an isolation valve. In the system and method according to one or more embodiments of the present disclosure, ratchet teeth or a collet mechanism of the hydraulic trigger may be used as a counting system to ensure that the isolation valve changes states only when a demanded count is reached.

In one or more embodiments of the present disclosure, movement of the inner axial cycling piston bar 20 in downward direction A by incremental distance W also moves the external profile 22 of the inner axial cycling piston bar 20 in downward direction A by incremental distance W. Because the external profile 22 of the inner axial cycling piston bar 20 is in mating engagement with the internal profile 34 of the core rod 24 in accordance with one or more embodiments of the present disclosure, movement of the external profile 22 of the inner axial cycling piston bar 20 in downward direction A by incremental distance W also causes the core rod 24 to move in downward direction A by incremental distance W. Because the core rod 24 is in cooperation with the power spring 28 within the housing assembly 14 as previously described, and as shown in

Returning to the operation of the ratchet assembly 18 of the hydraulic trigger system 10 for actuating the hydraulic valve 12 according to one or more embodiments of the present disclosure, as pressure bleeds off, cycling force F changes to upward direction B, which opposes downward direction A. When the cycling force F changes to upward direction B, the inner axial cycling piston bar 20 moves in upward direction B. In one or more embodiments of the present disclosure, movement of the inner axial cycling piston bar 20 in upward direction B also moves the external profile 22 of the inner axial cycling piston bar 20 in upward direction B, which causes the external profile 22 of the inner axial cycling piston bar 20 to collapse, disengage from the internal profile 34 of the core rod 24, and skip to re-engage the internal profile 34 of the core rod 24 at a location measuring the incremental distance W away. Because the outer ring 26 of the ratchet assembly 18 has an internal profile 38 that engages with the external profile of the core rod 24, and because the outer ring 26 may abut a stop 40 in the housing assembly 14 according to one or more embodiments of the present disclosure, the outer ring 26 prevents the core rod 24 from moving in upward direction B.
Thereafter, the previously described operational steps of the ratchet assembly 18 are repeated until the compression force of the power spring 28 causes the at least one shear screw 30 to shear, thereby releasing the power spring stopper 32. That is, each cycle will compress the power spring 28 by incremental distance W, and the compression force of the power spring 28 will continue to increase until the shear value of the at least one shear screw 30 is reached. The shear value of the at least one shear screw 30 is not limiting and depends on the application for which one or more embodiments of the present disclosure is being used. In one or more embodiments of the present disclosure, release of the power spring stopper 32 pushes the power spring stopper 32 in downward direction A, which actuates the hydraulic valve 12 of the hydraulic valve assembly 16 from a first position to a second position. According to one or more embodiments of the present disclosure, the hydraulic valve 12 may be a sleeve valve, a ball valve, an isolation valve, or a sliding sleeve, for example. In one or more embodiments of the present disclosure, actuating the hydraulic valve 12 from the first position to the second position changes a flow direction of the hydraulic valve 12. In one or more embodiments, actuating the hydraulic valve 12 from the first position to the second position opens the hydraulic valve 12. In other embodiments, actuating the hydraulic valve 12 from the first position to the second position closes the hydraulic valve 12.
As previously described, the ratchet assembly 18 or indexing mechanism according to one or more embodiments of the present disclosure may transition through a sequence of positions in response to the cycling of the cycling force F. Referring back to
In sum, in embodiments of the present disclosure where the piston 44 and the cycling spring 46 are connected to the inner axial cycling piston bar 20, as previously described, the cycling force F, which may be well pressure, differential pressure, or any other cycling pressure or force, for example, may be cycled up and downhole to correspondingly move the piston head 44(a). The movement of the piston head 44(a) may cycle the ratchet assembly 18 or indexing mechanism through a predetermined sequence of positions. For example, when the cycling force F increases to exert a upward force on the piston 44 including the piston head 44(a), the piston head 44(a) moves upwardly, and the cycling spring 46 resists the upwardly applied cycling force by exerting a downward force and resisting compression. When the cycling force F is relaxed so that the downward force generated by the cycling spring 46 exceeds the upward force that is exerted by the well pressure, the piston head 44(a) moves downwardly. In accordance with one or more embodiments of the present disclosure, each up and down cycle of the piston head 44(a) may cause the ratchet assembly 18 or indexing mechanism to transition to the next position in the sequence, as previously described.
Further, in embodiments of the present disclosure where the piston 44 and the cycling spring 46 are connected to the inner axial cycling piston bar 20, as previously described, the piston rod 44(b) of the piston 44 may extend beyond the housing assembly 14, as shown in
