Abstract
A tubing string assembly is disclosed for fluid treatment of a wellbore. The tubing string can be used for staged wellbore fluid treatment where a selected segment of the wellbore is treated, while other segments are sealed off. The tubing string can also be used where a ported tubing string is required to be run in in a pressure tight condition and later is needed to be in an open-port condition.
Claims (16)
1. An apparatus for fluid treatment of a borehole, the apparatus comprising a tubing string having a long axis, a first port opened through the wall of the tubing string, a second port opened through the wall of the tubing string, the second port offset from the first port along the long axis of the tubing string, a first packer operable to seal about the tubing string and mounted on the tubing string to act in a position offset from the first port along the long axis of the tubing string, a second packer operable to seal about the tubing string and mounted on the tubing string to act in a position between the first port and the second port along the long axis of the tubing string; a third packer operable to seal about the tubing string and mounted on the tubing string to act in a position offset from the second port along the long axis of the tubing string and on a side of the second port opposite the second packer; a first sleeve positioned relative to the first port, the first sleeve being moveable relative to the first port between a closed port position and a position permitting fluid flow through the first port from the tubing string inner bore and a second sleeve being moveable relative to the second port between a closed port position and a position permitting fluid flow through the second port from the tubing string inner bore; and a sleeve shifting means for moving the second sleeve from the closed port position to the position permitting fluid flow, the means for moving the second sleeve selected to create a seal in the tubing string against fluid flow past the second sleeve through the tubing string inner bore.
2. The apparatus of claim 1 wherein in the closed port position, the first sleeve is positioned over the first port to close the first port against fluid flow therethrough.
3. The apparatus of claim 1 wherein the first port has mounted thereon a cap extending into the tubing string inner bore and in the position permitting fluid flow, the first sleeve has engaged against and opened the cap.
4. The apparatus of claim 3 wherein in the position permitting fluid flow the first sleeve has sheared the cap.
5. The apparatus of claim 3 further comprising a third port having mounted thereon a cap extending into the tubing string inner diameter and in the position permitting fluid flow, the first sleeve also engages against the cap of the third port to open it.
6. The apparatus of claim 1 wherein the first port has mounted thereover a sliding sleeve and in the position permitting fluid flow, the first sleeve has engaged and moved the sliding sleeve away from a the first port.
7. The apparatus of claim 6 wherein the sliding sleeve includes a profile and the first sleeve includes a locking dog biased outwardly therefrom and selected to lock into the profile on the sleeve.
8. The apparatus of claim 6 wherein there is a third port with a sliding sleeve mounted thereover and the first sleeve is selected to engage and move the third port sliding sleeve after it has moved the sliding sleeve of the first port.
9. The apparatus of claim 1 wherein the means for moving the second sleeve is selected to move the second sleeve without also moving the first sleeve.
10. The apparatus of claim 1 wherein the second sleeve has formed thereon a seat and the means for moving the second sleeve includes a sealing device selected to seal against the seat, such that fluid pressure can be applied to move the second sleeve and the sealing device can seal against fluid passage past the second sleeve.
11. The apparatus of claim 10 wherein the sealing device is a plug.
12. The apparatus of claim 10 wherein the sealing device is a ball.
13. The apparatus of claim 1 wherein the first sleeve has formed thereon a first seat and the means for moving the first sleeve includes a first sealing device selected to seal against the first seat, such that once the first sealing device is seated against the first seat fluid pressure can be applied to move the first sleeve and the first sealing device can seal against fluid passage past the first sleeve and the second sleeve has formed thereon a second seat and the means for moving the second sleeve includes a second sealing device selected to seal against the second seat, such that when the second sealing device is seated against the second seat pressure can be applied to move the second sleeve and the second sealing device can seal against fluid passage past the second sleeve, the first seat having a larger diameter than the second seat, such that the second sealing device can move past the first seat without sealing thereagainst to reach and seal against the second seat.
14. The apparatus of claim 1 wherein at least one of the first, second and third packer is a solid body packer each including multiple packing elements.
