摘要： A tubular valving system includes, a tubular, a seat, a sleeve movably engaged with the seat between at least a first position, a second position and a third position, a release member between the sleeve and the seat that maintains the sleeve relative to the seat in the first position until release thereof, a biasing member configured to urge the sleeve from the second position toward the third position, and a flapper sealingly engagable with the seat. A first threshold pressure against the seated flapper causes release of the release member allowing the sleeve and the seat to attain the second position. A subsequently drop in pressure against the seated flapper below a second threshold level allows the biasing member to move the sleeve relative to the seat to the third position thereby unseating the flapper from the seat and preventing the flapper from again seating with the seat.

摘要： A flow tolerant actuating device includes, a first tubular having a first portion with a first minimum radial dimension, a second tubular surrounding the first tubular that is cyclically movable relative thereto having a second minimum radial dimension, and a protrusion extending from the second tubular having a third minimum radial dimension. The third minimum radial dimension is greater than the first minimum radial dimension and less than the second minimum radial dimension. The protrusion is positioned relative to the first minimum radial dimension in an upstream direction relative to an anticipated fluid flow direction, and the protrusion is configured to reduce downstream forces on the first tubular due to fluid flow.

摘要： A flow adapter includes an adapter body which defines a central axial flow bore and one or more lateral flow openings for fluid communication between the central flow bore and a production tubing flowbore surrounding the adapter. The central axial flow bore of the flow adapter provides a flow restriction which creates a pressure drop across the flow adapter. The flow restriction may be in the form of a conically tapered flowbore wherein the downstream end of the flowbore has a diameter that is less than the diameter of the upstream end of the flowbore.
