Drill fluid collecting device and method of use

1. A drill fluid collecting assembly for use between a power tong and a backup tong, the drill fluid collecting assembly comprising:

a shield disposed between the power tong and the backup tong;

a first seal assembly on the power tong; and

a second seal assembly on the backup tong, each seal assembly including a one-piece annular seal and a plate member, wherein the one-piece annular seal is disposed between the plate member and a clamp group of the respective tong and the one-piece annular seal is clamped against the clamp group of the respective tong by the plate member and one or more clamp hooks.

2. The drill fluid collecting assembly of claim 1 , wherein each seal assembly further includes at least one clamp hook configured to secure the plate member and the annular seal to the clamp group of the respective tong.

3. The drill fluid collecting assembly of claim 2 , wherein the at least one clamp hook is movable between a release position and a clamp position.

4. The drill fluid collecting assembly of claim 3 , wherein the plate member and the annular seal may be removed from the clamp group of the respective tong when the at least one clamp hook is in the release position.

5. The drill fluid collecting assembly of claim 2 , wherein the at least one clamp hook is L-shaped and rotatable between a release position and a clamp position.

6. The drill fluid collecting assembly of claim 1 , wherein an upper portion of the shield is movable relative to the power tong by a plurality of cylinders attached to the backup tong.

7. The drill fluid collecting assembly of claim 1 , further including a drain for transporting fluid from the space between the power tong and the backup tong.

8. The drill fluid collecting assembly of claim 1 , wherein the first seal assembly creating a seal between a first portion of a tubular string and the power tong.

9. The drill fluid collecting assembly of claim 8 , wherein the second seal assembly creating a seal between a second portion of the tubular string and the backup tong.

10. The drill fluid collecting assembly of claim 1 , wherein the first seal assembly is disposed on a lower portion of the power tong and the second seal assembly is disposed on an upper portion of the backup tong.

11. A method of collecting fluid between a power tong and a backup tong, the method comprising:

attaching a shield between the power tong and the backup tong;

creating a seal between a first portion of a tubular string and the power tong using a first one-piece annular seal that is clamped between a first plate and the power tong by one or more hook clamps;

creating a seal between a second portion of the tubular string and the backup tong using a second one-piece annular seal that is clamped between a second plate and the backup tong by one or more hook clamps; and

collecting fluid in a space between the power tong and the backup tong.

12. The method of claim 11 , further comprising transporting fluid from the space between the power tong and the backup tong to a fluid receiving unit.

13. The method of claim 11 , wherein each annular seal is attached to a clamp group of the respective tong by a plate and a clamp member.

14. The method of claim 13 , wherein the clamp member is rotatable between a release position and a clamp position.

15. A drill fluid collecting assembly for use between a power tong and a backup tong, the drill fluid collecting assembly comprising:

a shield disposed between the power tong and the backup tong;

a first one-piece annular seal having a first side in contact with a clamp group of the power tong and a second side in contact with a first clamp plate member, wherein the first one-piece annular seal is clamped against the power tong by the first clamp plate and one or more hook clamps; and

a second one-piece annular seal having a first side in contact with a clamp group of the backup tong and a second side in contact with a second clamp plate member, wherein the second one-piece annular seal is clamped against the backup tong by the second clamp plate and one or more hook clamps.

16. The drill fluid collecting assembly of claim 15 , wherein at least one hook clamp is used to attach the annular seal and clamp plate to the clamp group of the respective tong.

17. The drill fluid collecting assembly of claim 16 , wherein the at least one hook clamp is rotatable between a release position and a clamp position.

18. A drill fluid collecting assembly for use between a power tong and a backup tong, each tong having a clamp group and a clamp member, the drill fluid collecting assembly comprising:

a shield disposed between the power tong and the backup tong;

a first seal assembly on the power tong; and

a second seal assembly on the backup tong, each seal assembly including an annular seal that is clamped against the clamp group of the respective tong by a plate member and one or more clamp hooks, wherein the clamp member of the respective tong is movable relative to the annular seal.

19. The drill fluid collecting assembly of claim 18 , wherein the annular seal is a one-piece annular seal member.

20. A method of collecting fluid in a space between a power tong and a backup tong, the method comprising:

creating a seal between a tubular string and the power tong using a first annular seal;

moving a clamp member of the power tong between a retracted position and a grip position while maintaining the seal between the tubular string and the power tong;

creating a seal between the tubular string and the backup tong using a second annular seal;

moving a clamp member of the backup tong between a retracted position and a grip position while maintaining the seal between the tubular string and the backup tong; and

collecting fluid in the space between the power tong and the backup tong.

21. The method of claim 20 , wherein each annular seal is a one-piece annular seal member.
