Method and apparatus for drilling and servicing subterranean wells with rotating coiled tubing

1. A system for managing control lines associated with coiled tubing well operations equipment, comprising:

a floor having a platform that can rotate relative thereto, the platform having operations equipment thereon;

a control line swivel that supports one or more operation equipment control lines above the floor;

at least one control line extending between the swivel and well operations equipment on the platform for controlling operation of the equipment;

a torque member having a first end coupled to the platform and a second end coupled to a rotatable portion of the swivel;

a support member having a first end coupled to the floor and a second end coupled to a non-rotatable portion of the swivel;

the swivel, torque member and support member configured such that as the platform rotates relative to the floor, the torque member causes the rotatable portion of the swivel to rotate therewith; and

at least one adjustment member coupled to the support member for moving the swivel into and out of position.

2. The system of claim 1 , wherein the torque member and support member are A-frames.

3. The system of claim 1 , wherein the at least one adjustment member includes a hydraulic cylinder.

4. The system of claim 1 , further comprising:

a second platform that can rotate relative to either or both of the floor and first platform, the second platform having at least one well operation equipment thereon; and

a control line extending from the least one well operation equipment to the rotatable portion of the swivel.

5. The system of claim 1 , wherein the control lines convey pneumatic fluid, hydraulic fluid or electricity to the equipment.

6. The system of claim 4 , wherein the support member supports at least the weight of the swivel, the control lines and any control fluid.

7. The system of claim 6 , wherein the control lines convey pneumatic fluid, hydraulic fluid or electricity to the equipment.

8. The system of claim 6 , wherein the swivel conveys hydraulic control fluid, pneumatic control fluid and electrical control.

9. The system of claim 1 , wherein the support member supports at least the weight of the swivel, the control lines and any control fluid.

10. The system of claim 1 , wherein the swivel conveys hydraulic control fluid, pneumatic control fluid and electrical control.

11. A method of drilling or servicing a well, comprising:

providing a floor assembly oriented about a well, the floor assembly including equipment having operation lines;

providing a first rotating structure associated with the floor and having an axis of rotation substantially aligned with an axis of the well, and comprising a coiled tubing reel assembly and a counterbalance assembly;

providing a second rotating structure associated with the floor and having an axis of rotation substantially aligned with the well axis, and comprising a tubing injector;

providing a swivel support assembly that supports a swivel located above the well;

positioning the longitudinal axis of the swivel in substantial alignment with the axis of the well;

supporting at least one operation line with the swivel;

uncoiling tubing off of the reel and into the injector;

injecting the uncoiled tubing into the well;

adjusting the position of the reel assembly to maintain the coiled tubing in substantial alignment with the well;

adjusting the counterbalance assembly to balance the first rotating structure as tubing is uncoiled;

rotating the first rotating structure to thereby rotate the uncoiled tubing in the well; and

determining any differential torque between the first rotating structure and the second rotating structure.

12. The method of claim 11 , wherein the well is under balanced.

13. The method of claim 11 , wherein the well is overbalanced.

14. A method of drilling or servicing a well with coiled tubing, comprising:

providing a first rotatable platform having an axis of rotation substantially aligned with an axis of the well;

associating a coiled tubing reel assembly and a counterbalance assembly in operable arrangement on the first platform;

providing a second rotating platform having an axis of rotation substantially aligned with the well axis, and having a coiled tubing injector operably associated therewith;

providing a non-rotatable support assembly above the well;

coupling an equipment operation line swivel to the support assembly above the well;

positioning the swivel above and adjacent the well axis;

supporting at least one operation line from the swivel to equipment on the first rotatable platform and from the swivel to equipment on the second rotatable platform;

uncoiling tubing off the reel and into the injector;

injecting the uncoiled tubing into the well;

rotating the first rotatable platform to thereby rotate the uncoiled tubing in the well;

conveying fluid or electricity through the swivel to the equipment on the first platform while the first platform is rotating; and

conveying fluid or electricity through the swivel to the equipment on the second platform while the first platform is rotating.

15. The method of claim 14 , further comprising:

adjusting the position of the reel assembly to maintain the coiled tubing in substantial alignment with the well axis as the first platform rotates;

adjusting the counterbalance assembly to balance the first rotatable platform as tubing is uncoiled.

16. The method of claim 14 , further comprising:

positioning a rotational axis of the swivel in substantial alignment with the well axis.

17. The method of claim 14 , wherein the swivel is configured to allow relative rotation between the at least one first platform operation line and the at least one second platform operation line.

18. The method of claim 14 , further comprising:

changing operation of at least one of the equipment on the first and second platform by the fluid or electricity conveyed through the swivel.
