Abstract

What is provided is a method and apparatus wherein a swivel can be detachably connected to an annular blowout preventer thereby separating the drilling fluid or mud into upper and lower sections and allowing the fluid to be displaced in two stages, such as while the drill string is being rotated and/or reciprocated. In one embodiment the sleeve or housing can be rotatably and sealably connected to a mandrel. The swivel can be incorporated into a drill or well string and enabling string sections both above and below the sleeve to be rotated in relation to the sleeve. In one embodiment the drill or well string does not move in a longitudinal direction relative to the swivel. In one embodiment, the drill or well string does move longitudinally relative to the sleeve or housing of the swivel.

Claims

1. A method of using a reciprocating swivel in a drill or work string, the method comprising the following steps:

(a) lowering a rotating and reciprocating tool to an annular BOP, the tool comprising a mandrel and a sleeve, the sleeve being reciprocable relative to the mandrel and the swivel including a quick lock/quick unlock system which has locked and unlocked states, the swivel including an interstitial space between the sleeve and the mandrel, the interstitial space having a interstitial pressure relief mode and non-pressure relief modes, the swivel being reversably switchable between pressure relief and non-pressure relief modes;

(b) after step “

a”

, having the annular BOP close on the sleeve;

(c) after step “

b”

, causing relative longitudinal movement between the sleeve and the mandrel and activating the quick lock/quick unlock system to cause the quick lock/quick unlock to change from an unlocked to a locked state.

2. The method of claim 1, wherein in step “

a”

, the sleeve is longitudinally locked relative to the mandrel.

3. The method of claim 1, wherein, after step “

b” and

before step “

c”

, the sleeve is unlocked longitudinally relative to the mandrel.

4. The method of claim 1, wherein, after step “

c”

, the sleeve is longitudinally locked relative to the mandrel.

5. The method of claim 1, wherein during step “

c”

operations are performed in the wellbore.

6. The method of claim 1, wherein after step “

c”

operations are performed in the wellbore.

7. The method of claim 1, wherein after step “

c”

the tool is fluidly connected to a string having a bore and fluid is pumped through at least part of the string'"'"'s bore.

8. The method of claim 1, wherein the quick lock/quick unlock system is radially aligned before being activated and in a locked state.

9. The method of claim 1, wherein the quick lock/quick unlock system can rotate relative to the sleeve when activated and in a locked state.

10. The method of claim 1, wherein the sleeve includes at least one catch for restricting relative longitudinal movement between the sleeve and the annular BOP when the annular BOP is sealed on the sleeve.

11. The method of claim 10, wherein the sleeve includes two catches spaced apart on the longitudinal ends of the sleeve.

12. The method of claim 10, wherein the at least one catch includes a detachable attachment, the detachable attachment being configured to mate with the annular BOP.

13. The method of claim 12, wherein the detachable attachment includes two pieces which are detachably connectable to the sleeve.

14. The method of claim 12, wherein a plurality of detachable attachments are includes for allowing the catch to fit a plurality of annular BOPs, the annular BOPs being manufactured by a plurality of manufacturers.

15. A method of using a reciprocating swivel in a drill or work string, the method comprising the following steps:

(a) lowering a rotating and reciprocating tool to an annular BOP, the tool comprising a mandrel and a sleeve, the sleeve being reciprocable relative to the mandrel and the swivel including a quick lock/quick unlock system which has locked and unlocked states;

(b) after step “

a”

, having the annular BOP close on the sleeve; and

causing relative longitudinal movement between the sleeve and the mandrel and causing the quick lock/quick unlock system to change from an unlocked state to a locked state;

(c) after step “

b”

, moving the sleeve outside of the annular BOP;

(d) after step “

c”

, moving the sleeve inside of the annular BOP and having the annular BOP close on the sleeve; and

(e) after step “

d”

, causing relative longitudinal movement between the sleeve and the mandrel and activating the quick lock/quick unlock system.

16. The method of claim 15, wherein in step “

a”

, the sleeve is longitudinally locked relative to the mandrel.

17. The method of claim 15, wherein, after step “

b”

, the sleeve is unlocked longitudinally relative to the mandrel.

18. The method of claim 15, wherein, after step “

c”

, the sleeve is longitudinally locked relative to the mandrel.

19. The method of claim 15, wherein during step “

c”

operations are performed in the wellbore.
