Abstract
A dual tubing coiled tubing string, including methods of assembly, that includes an inner tubing (IT) sealed by a seal (SL) within at least an upper portion of an outer tubing (OT).
Claims (16)
1. A coiled tubing system for circulating fluids in a wellbore comprising:
a coiled tubing string;
a check valve attached to the coiled tubing string, the check valve having a fluid passageway therethrough and a biased flapper wherein the flapper is biased to close the fluid passageway to prevent fluid flow up through the check valve and into the coiled tubing string, the biasing force may be overcome to allow fluid flowed down the coiled tubing string and through the check valve; and a shiftable sleeve located in the fluid passageway of the check valve wherein the sleeve is shiftable from a first position where the sleeve prevents the flapper from closing the fluid passageway to allow reverse circulating through the valve and a second position where the biasing force may bias the flapper to close the fluid passageway.
a coiled tubing string;
a check valve attached to the coiled tubing string, the check valve having a fluid passageway therethrough and a biased flapper wherein the flapper is biased to close the fluid passageway to prevent fluid flow up through the check valve and into the coiled tubing string, the biasing force may be overcome to allow fluid flowed down the coiled tubing string and through the check valve; and a shiftable sleeve located in the fluid passageway of the check valve wherein the sleeve is shiftable from a first position where the sleeve prevents the flapper from closing the fluid passageway to allow reverse circulating through the valve and a second position where the biasing force may bias the flapper to close the fluid passageway.
2. The coiled tubing system of claim 1 wherein the coiled tubing string is a coil-in-coil tubing string.
3. The coiled tubing system of claim 1 wherein the shiftable sleeve includes a ball seat for receiving a ball wherein the sleeve may be shifted from the first position to the second position by fluid pressure applied to the ball when the ball is located in the ball seat.
4. The coiled tubing system of claim 1 wherein the sleeve is initially sheer pinned in the first position.
5. The coiled tubing system of claim 1 further comprising a frangible burst disk proximate to the leading end of the coiled tubing string to initially seal the coiled tubing string from wellbore fluids.
6. The coiled tubing system of claim 1 wherein the check valve is proximate to the leading end of the coiled tubing string.
7. A method of circulating fluids through a coiled tubing string comprising the steps of:
providing a cyclic check valve in the coil tubing string;
positioning the coil tubing string in a wellbore wherein an annulus is created about the outer diameter of the coiled tubing string;
circulating fluid down the annulus and up through the check valve and into the coiled tubing string; and cycling the check valve to prevent fluid flow from flowing up through the valve and into the coiled tubing.
providing a cyclic check valve in the coil tubing string;
positioning the coil tubing string in a wellbore wherein an annulus is created about the outer diameter of the coiled tubing string;
circulating fluid down the annulus and up through the check valve and into the coiled tubing string; and cycling the check valve to prevent fluid flow from flowing up through the valve and into the coiled tubing.
8. The method of claim 7 further comprising providing a second smaller diameter coiled tubing string inside of the first coiled tubing string.
9. The method of claim 7 comprising the step of providing a shiftable sleeve within the check valve, and wherein the cycling step further comprises shifting the sleeve from a first position where fluid may be circulated up through the valve and into the coiled tubing.
10. The method of claim 7 further comprising shifting the sleeve from the first position to the second position by hydraulic pressure acting on a ball and ball seat arrangement on the sleeve.
11. The method of claim 7 further comprising providing a biased flapper in a fluid passageway in the check valve and shifting the sleeve from the first position to the second position wherein the sleeve holds the flapper open in the first position and the flapper may be biased closed when the sleeve is shifted to the second position.
12. A coiled tubing assembly for circulating fluid in a wellbore comprising:
a coiled tubing string, the string having a first end attached to a reel and a distal end for lowering into the wellbore;
a cyclic check valve attached proximate to the distal end of the coiled tubing string, the check valve having a fluid passageway therethrough and a valve closure means for preventing fluid flow up through the fluid passageway of the check valve and into the coiled tubing string; and a means for activating the valve closure means.
a coiled tubing string, the string having a first end attached to a reel and a distal end for lowering into the wellbore;
a cyclic check valve attached proximate to the distal end of the coiled tubing string, the check valve having a fluid passageway therethrough and a valve closure means for preventing fluid flow up through the fluid passageway of the check valve and into the coiled tubing string; and a means for activating the valve closure means.
13. The coiled tubing assembly of claim 12 wherein the valve closure means is a biased flapper wherein the flapper has a biasing force that may be overcome to allow fluid flow down the coiled tubing and out the check valve.
14. The coiled tubing assembling of claim 13 wherein the means for activating the biased flapper is a shiftable sleeve wherein the sleeve is shiftable from a first position where the flapper is help open and a second position where the flapper is biased closed.
15. The coiled tubing assembly of claim 14 wherein the shiftable sleeve further comprises a ball seat for receiving a ball wherein the sleeve may be shifted form the first position to the second position by fluid pressure applied to the ball when the ball is located in the ball seat.
16. The coiled tubing assembly of claim 12 further comprising a second, smaller diameter coiled tubing string extending inside of the first coiled tubing string.
