摘要： Provided is an electrically surface-controlled subsurface safety valve (ESCSSV). The ESCSSV, in one example, includes an outer housing comprising a central bore extending axially through the housing that is configured to convey production fluids there through. The ESCSSV, in this embodiment, further includes a valve closure mechanism disposed proximate a downhole end of the central bore, and a bore flow management actuator disposed in the central bore and configured to move between a closed state and a flow state to engage or disengage the valve closure mechanism to determine a flow condition of the production fluids through the central bore. The ESCSSV, in this embodiment, additionally includes an electric valve assembly fluidically coupled to the bore flow management actuator and configured to select between a section pressure or the annulus pressure to control the bore flow management actuator and determine the flow condition of production fluids through the central bore.

摘要： An exercise tool assembly for operating a downhole tool auxiliary to a primary actuator system of the downhole tool includes a cylinder mandrel configured to be received in the central bore of the downhole tool. A piston mandrel is in and sealed with the cylinder mandrel. The exercise tool assembly is configured to couple to an actuator sleeve of the downhole tool and to couple to the downhole tool at a location apart from the actuator sleeve. The piston mandrel is responsive to a change in pressure in the central bore to translate relative to the cylinder mandrel and translate the coupling with the actuator sleeve relative to the coupling at the location apart from the actuator sleeve.

摘要： A well system includes a tubing string and a subsurface safety valve interconnected with the tubing string and including a housing that defines a central flow passageway and includes a flapper pivotable within the central flow passageway between closed and open positions. A flow tube is positioned within the central flow passageway and engageable with the flapper to move the flapper to the open position. An actuation piston is operatively coupled to the flow tube, a balance piston is operatively coupled to the flow tube, and a lock-open piston is engageable with an actuator sleeve operatively coupled to the flow tube. A lock-open tool is positionable within the central flow passageway to convey hydraulic pressure into a lock-open piston bore and thereby actuate the lock-open piston to an actuated position that moves the flow tube and permanently locks the flapper in the open position.

摘要： A downhole circulating valve includes a generally tubular outer housing having an axially extending internal passageway including an internal seat and at least one generally radially extending opening formed through the housing intersecting the internal seat. A valve element is rotatably disposed within the internal passageway. The valve element has an axially extending internal bore and a head portion disposed at least partially within the internal seat. The head portion includes at least one generally radially extending seal element. The valve element has a first position relative to the housing, wherein the seal element is not aligned with the opening, thereby allowing fluid communication between the opening and the internal passageway. The valve element has a second position relative to the housing, wherein the seal element is aligned with the opening and wherein the seal element forms a metal-to-metal seal with the internal seat, thereby preventing fluid communication between the opening and the internal passageway.
