Pipe drive sealing system and method

1. A pipe drive system, comprising:

a gripping device configured to engage an outer surface of a drillpipe element to be positioned within a wellbore;

a top drive configured to impart rotational force to the gripping device;

a housing of the gripping device configured to extend over and at least partially around a distal end of the drillpipe element;

a seal area positioned along an inner perimeter of the housing such that, when a seal is inserted in the seal area, the seal is arranged to axially abut and engage with an axial face of the distal end of the drillpipe element and an axial face of the gripping device relative to a longitudinal axis of the gripping device; and

engagement features of the gripping device configured to extend inwardly from the inner perimeter to facilitate coupling of the gripping device with an outer circumferential area of the drillpipe element.

2. The system of claim 1 , comprising the seal, wherein the seal is coupled to the axial face of the gripping device via a friction fit or via adhesive.

3. The system of claim 1 , comprising the drillpipe element and the seal, wherein the seal is removably positioned and pressed between the axial face of the distal end of the drillpipe element and the axial face of the gripping device.

4. The system of claim 1 , wherein the seal area includes a receptacle in the axial face of the gripping device.

5. The system of claim 1 , comprising the seal, wherein a pressure sealed by the seal is proportional to a force applied to the seal between the seal area and the axial face of the distal end of the drillpipe element.

6. The system of claim 1 , comprising the seal and a filler neck, wherein the filler neck is configured to extend into the drillpipe element when the distal end of the drillpipe element is disposed within the gripping device such that the seal is pressed between the axial face of the distal end of the drillpipe element and the axial face of the gripping device, wherein the filler neck includes a channel configured to facilitate fluid flow into the drillpipe element from a fluid pump.

7. The system of claim 6 , wherein the filler neck is sized to extend past threads of the distal end of the drillpipe element when the distal end of the drillpipe element is disposed within the gripping device such that the seal is pressed between the axial face of the distal end of the drillpipe element and the axial face of the gripping device.

8. The system of claim 1 , wherein the engagement features comprise pads configured to frictionally engage the outer circumferential area of the drillpipe element.

9. The system of claim 8 , wherein the pads include patterns configured to function as wickers for frictionally engaging the outer circumferential area of the drillpipe element.

10. A gripping device, comprising:

a housing including a receptacle, wherein the receptacle includes an axial receptacle face and a receptacle boundary extending from a perimeter of the axial receptacle face;

an engagement feature coupled with the housing and configured to be actuated to engage an outer circumferential area of a drillpipe element to be positioned within a wellbore when the housing is extending over a distal end of the drillpipe element; and

a seal positioned within an inner boundary of the housing, wherein the seal is arranged to engage with an axial drillpipe face of the distal end of the drillpipe element and the axial receptacle face within the housing relative to a longitudinal axis of the gripping device.

11. The gripping device of claim 10 , comprising a filler neck configured to extend into the drillpipe element when the distal end of the drillpipe element is disposed within the housing such that the seal is pressed between the axial receptacle face and the axial drillpipe face, wherein the filler neck includes a channel configured to facilitate fluid flow into the drillpipe element.

12. The gripping device of claim 11 , wherein the filler neck is sized to extend past threads of the distal end of the drillpipe element when the distal end of the drillpipe element is disposed within the housing such that the seal is pressed between the axial receptacle face and the axial drillpipe face.

13. The gripping device of claim 10 , comprising a coupling mechanism configured to facilitate coupling of the gripping device with a pipe drive system such that the pipe drive system can impart motion to the gripping device.

14. The gripping device of claim 10 , wherein the engagement feature comprises a plurality of pads with patterned gripping surfaces to facilitate frictional engagement with the outer circumference of the drillpipe element.

15. The gripping device of claim 10 , wherein the axial receptacle face comprises a groove shaped recess to receive the seal.

16. A method of assembling or disassembling a drill string, comprising:

extending a housing of a gripping device over a distal end of a drillpipe element to be positioned within a wellbore such that a boundary of the housing extending from a perimeter of an axial face of the gripping device surrounds a circumferential area of the drillpipe element;

pressing a seal between the axial face of the gripping device and an axial face of the drillpipe element relative to a longitudinal axis of the gripping device; and

engaging the circumferential area of the drillpipe element with an engagement feature of the gripping device.

17. The method of claim 16 , wherein engaging the circumferential area comprises engaging gripping pads of the gripping device with the circumferential area of the drillpipe element.

18. The method of claim 16 , comprising stabbing a filler neck that extends from an inner perimeter of the axial face of the gripping device into the drillpipe element.

19. The method of claim 18 , comprising rotating the gripping device to impart rotation to the drillpipe element to facilitate attachment or detachment of the drillpipe element with a drill string while passing fluid through the filler neck into the drill string.

20. The method of claim 18 , comprising retaining the seal against the axial face of the gripping device with a fastener.
