Abstract

Present embodiments are directed to a circulation system including a circulation management system. A housing of a coupling feature of the circulation management system is configured to extend over a box end of a pipe element. A seal disposed within the housing is configured to engage with a face of the box end. A force-application feature is configured to force the seal against the face of the box end to establish a sealed engagement between the circulation management system and the pipe element. A flow path of the circulation management system extends through the housing and the seal, wherein the flow path facilitates fluid flow into the pipe element from the circulation management system when the sealed engagement is established. A port to the flow path is configured to couple with a fluid flow supply feature.

First claim

The invention claimed is:

1. A circulation system, comprising:
a circulation management system;
a coupling feature of the circulation management system;
a housing of the coupling feature configured to extend over a box end of a pipe element;
a seal disposed within the housing and configured to engage with a face of the box end;
a force-application feature configured to force the seal against the face of the box end to establish a sealed engagement between the circulation management system and the pipe element;
a flow path of the circulation management system, the flow path extending through the housing and the seal, wherein the flow path facilitates fluid flow into the pipe element from the circulation management system when the sealed engagement is established;
a port to the flow path, wherein the port is configured to couple with a fluid flow supply feature;
a piston assembly configured to coordinate with the force-application feature to establish the sealed engagement, wherein the piston assembly comprises a hollow piston with the seal disposed about the piston at an end of the piston opposite the port, and wherein the piston assembly is configured to move relative to the housing; and
a piston housing and first and second ports into the piston housing, wherein a lip of the piston is disposed within the piston housing such that the seal and an additional seal are positioned on opposite sides of the lip, the first and second ports into the piston housing being on opposite sides of the lip to facilitate hydraulic actuation of the piston assembly.

2. The system of claim 1 , wherein the force-application feature comprises elevators configured to engage a shoulder of the box end to establish support for forcing the seal against the face.

3. The system of claim 1 , wherein the piston assembly is configured to be at least partially actuated by pressure from fluid flow against the additional seal disposed about the piston at an end of the piston proximate the port.

4. The system of claim 1 , wherein the circulation management system comprises a mechanical arm and base configured to maneuver the housing over the box end.

5. The system of claim 1 , comprising a valve configured to direct fluid flow from a general fluid circulation system to the port or from the general fluid circulation system to a pipe management system.

6. The system of claim 1 , comprising a secondary passage into the flow path.

7. The system of claim 6 , wherein the secondary passage comprises a wireline port configured to receive a wireline during operation of the circulation management system.

8. A circulation system, comprising:
a circulation management system;
a coupling feature of the circulation management system;
a housing of the coupling feature configured to extend over a box end of a pipe element;
a seal disposed within the housing and configured to engage with a face of the box end;
a force-application feature configured to force the seal against the face of the box end to establish a sealed engagement between the circulation management system and the pipe element;
a flow path of the circulation management system, the flow path extending through the housing and the seal, wherein the flow path facilitates fluid flow into the pipe element from the circulation management system when the sealed engagement is established;
a port to the flow path, wherein the port is configured to couple with a fluid flow supply feature; and
a secondary passage into the flow path, wherein the secondary passage comprises a wireline port configured to receive a wireline during operation of the circulation management system.

9. The system of claim 8 , wherein the force-application feature comprises elevators configured to engage a shoulder of the box end to establish support for forcing the seal against the face.

10. The system of claim 8 , comprising a piston assembly configured to coordinate with the force-application feature to establish the sealed engagement, wherein the piston assembly comprises a hollow piston with the seal disposed about the piston at an end of the piston opposite the port, and wherein the piston assembly is configured to move relative to the housing.

11. The system of claim 10 , wherein the piston assembly is configured to be at least partially actuated by pressure from fluid flow against an additional seal disposed about the piston at an end of the piston proximate the port.

12. The system of claim 10 , comprising a piston housing and first and second ports into the piston housing, wherein a lip of the piston is disposed within the piston housing such that the seal and an additional seal are positioned on opposite sides of the lip, the first and second ports into the piston housing being on opposite sides of the lip to facilitate hydraulic actuation of the piston assembly.

13. The system of claim 8 , wherein the circulation management system comprises a mechanical arm and base configured to maneuver the housing over the box end.

14. The system of claim 8 , comprising a valve configured to direct fluid flow from a general fluid circulation system to the port or from the general fluid circulation system to a pipe management system.
