Abstract

Present embodiments are directed to a drilling fluid management device. A containment structure of the drilling fluid management device is capable of engaging and at least partially creating a seal with a drillpipe element or drillpipe handling equipment. Further, a suction port structure of the drilling fluid management device extends from the containment structure and includes an opening into the containment structure, wherein the suction port structure is designed to couple with a drilling fluid transport feature.

First claim

The invention claimed is:

1. A system, comprising:
a drilling fluid management device;
a containment structure of the drilling fluid management device configured to engage and at least partially create a seal with a drillpipe element or drillpipe handling equipment;
a suction port structure of the drilling fluid management device extending from the containment structure and including an opening into the containment structure, wherein the suction port structure is configured to couple with a drilling fluid transport feature; and
a diverter valve configured to direct a drilling fluid from a pipe drive system to a venturi portion of the suction port structure.

2. The system of claim 1 , wherein the suction port structure comprises a suction passage communicatively coupled to the venturi portion of the suction port structure, wherein the suction passage extends out from the containment structure and the venture portion is transverse to the suction passage.

3. The system of claim 2 , wherein inner walls of the venturi portion of the suction port structure narrow from a broad opening to a narrow passage via a constriction.

4. The system of claim 3 , wherein the suction passage and the venturi portion intersect proximate the narrow passage.

5. The system of claim 3 , comprising a drilling fluid supply coupled to a first end of the venturi portion via a conduit such that the system is configured to flow drilling fluid from the first end to a second end and such that the narrow passage is downstream of the broad opening with respect to the flow.

6. The system of claim 5 , wherein the suction passage and the venturi portion intersect at least partially downstream of the constriction.

7. The system of claim 1 , wherein the opening is arranged to align with a face of the drillpipe element or drillpipe handling equipment.

8. The system of claim 1 , comprising a suction side of a pump coupled with the suction port structure.

9. The system of claim 1 , comprising a positioning lip extending at least partially around an inner perimeter of the containment structure and configured to align with a face of a drillpipe when the containment structure is engaged about the drillpipe.

10. The system of claim 1 , comprising a sealing pad extending around a portion of an inner surface of the containment structure and configured to establish a sealed engagement with a surface of the drillpipe element or the drillpipe handing equipment when the containment structure is engaged about the drillpipe element or the drillpipe handling equipment.

11. The system of claim 1 , comprising a drillpipe, wherein the containment structure is sealed about a box end of the drillpipe via engagement between a sealing pad of the containment structure and an outer surface of the box end.

12. The system of claim 1 , comprising a pair of drillpipes coupled together, wherein the containment structure is sealed about a box end of a first of the pair of drillpipes and a pin end of a second of the pair of drillpipes such that the opening is aligned with a face of the box end of the first of the pair of drillpipes.

13. The system of claim 1 , comprising a venturi bank communicatively coupled with the suction port structure, wherein the suction port structure comprises a suction passage including a plurality of flow paths communicatively coupled with the containment structure.

14. The system of claim 13 , comprising a suction manifold operating as the drilling fluid transport feature and coupling the venturi bank with the suction port structure.

15. A method, comprising:
coupling a containment structure of a drilling fluid management device about a drillpipe element such that at least a partial seal is established between a lower end of the containment structure and the drillpipe element below a face of an opening of the drillpipe element;
applying a suction within the containment structure via a suction port structure of the drilling fluid management device that includes an opening into the containment structure;
transporting drilling fluid from within the drilling fluid management device to a drilling fluid retention tank from the suction port structure; and
operating a diverting valve to direct the drilling fluid from a pipe drive system to the suction port structure.

16. The method of claim 15 , wherein applying the suction comprises generating a Venturi effect within the suction port by passing drilling fluid from one end of a venturi portion of the suction port structure to a second end of the venturi portion of the suction port structure.

17. The method of claim 16 , comprising operating the diverting valve to direct the drilling fluid from the pipe drive system to the venturi portion of the suction port structure.

18. The method of claim 15 , wherein applying the suction comprises generating a suction with a venturi bank comprising a plurality of venturis communicatively coupled with the suction port structure.

19. A system, comprising:
a drillpipe element;
a drilling fluid management device;
a containment structure of the drilling fluid management device coupled about the drillpipe element;
a suction port structure coupled with the containment structure and including an opening into the containment structure;
a suction manifold communicatively coupled with the suction port structure and including a valve configured to seal the suction manifold away from the suction port structure;
a venturi bank including a plurality of venturis communicatively coupled with the suction manifold along a main flow path of each venturi and down stream of a constriction in each venturi; and
a drilling fluid pumping system configured to pump drilling fluid through the main flow path of each venturi.
