Abstract

Official abstract text for this publication.

A fill-up and circulation tool includes a central assembly including a mandrel, a nose assembly disposed at a terminal end of the mandrel, an outer assembly coupled to the central assembly, and a valve configured to change position between a closed position and an open position, wherein changing position between the closed position and the open position includes movement of the outer assembly relative to the central assembly.

First claim

Opening claim text (preview).

What is claimed is: 1. A fill-up and circulation tool comprising: a central assembly including: a mandrel; and a nose assembly disposed at a terminal end of the mandrel, the nose assembly including an opening; an outer assembly coupled to the central assembly; a biasing member disposed between a portion of the outer assembly and a portion of the central assembly: a valve configured to change position between a closed position and an open position based on movement of the biasing member from an initial stale to a compressed state, wherein changing position between the closed position and the open position includes relative movement of the outer assembly to the central assembly including the nose assembly and wherein the opening in the nose assembly Is configured to be exposed based on the relative movement of the outer assembly to the central assembly including movement of the biasing member from the initial state to the compressed state. 2. The fill-up and circulation tool of claim 1 , wherein changing position between the closed position and the open position includes longitudinal movement of the central assembly relative to the outer assembly. 3. The fill-up and circulation tool of claim 1 , wherein changing position between the closed position and the open position includes longitudinal movement of the nose assembly relative to the outer assembly. 4. The fill-up and circulation tool of claim 1 , wherein changing position between the closed position and the open position includes longitudinal movement of the nose assembly relative to a centralizer. 5. The fill-up and circulation tool of claim 4 , wherein the outer assembly includes the centralizer. 6. The fill-up and circulation tool of claim 1 , wherein changing position between the closed position and the open position includes longitudinal movement of the nose assembly relative to a sealing sleeve. 7. The fill-up and circulation tool of claim 1 , wherein the mandrel comprises an interior passage defining a portion of a fluid flow passage. 8. The fill-up and circulation tool of claim 1 , wherein in the open position a fluid flow passage extends through the entirety of the tool. 9. The fill-up and circulation tool of claim 1 , wherein in the closed position a fluid flow passage is terminated within the interior of the tool. 10. The fill-up and circulation tool of claim 1 , wherein the opening of the nose assembly is configured to be exposed with a change in position of the valve between the closed position and the open position. 11. The fill-up and circulation tool of claim 10 , wherein in the closed position at least a portion of the opening is adjacent an interior surface of a centralizer. 12. The fill-up and circulation tool of claim 10 , wherein in the open position the opening is longitudinally displaced from an interior surface of a centralizer. 13. The fill-up and circulation tool of claim 10 , wherein in the open position the opening is longitudinally displaced from an interior surface of a component positioned proximate an end of the outer assembly. 14. The fill-up and circulation tool of claim 1 , wherein the nose assembly comprises a plurality of openings defining a fluid flow passage through the nose assembly. 15. The fill-up and circulation tool of claim 1 , further comprising a centralizer coupled to the outer assembly and configured to align the tool within a tubular. 16. The fill-up and circulation tool of claim 1 , wherein the outer assembly further comprises a packer configured to form a seal between the tool and an inner surface of a tubular. 17. The fill-up and circulation tool of claim 1 , wherein changing position between the closed position and the open position is based upon a difference in forces between a force applied by the biasing member relative to a force applied in the opposite direction by a fluid contained in the central assembly. 18. The fill-up and circulation tool of claim 1 , wherein in the closed position the valve comprises a sealing ratio (Fb/Ff) of at least about 1, wherein Fb represents a force configured to be applied by the biasing member against the central assembly and Ff represents a force configured to be applied by a fluid contained in the central assembly against the outer assembly. 19. The fill-up and circulation tool of claim 1 , wherein the outer assembly comprises a push plate configured to facilitate actuation of the valve from the closed position to the open position. 20. The fill-up and circulation tool of claim 19 , wherein the push plate is configured to engage a portion of the mandrel in the open position.
