摘要： A control system for an annulus balanced subsurface safety valve. A system for operating a safety valve in a well includes a piston of the safety valve being responsive to displace due to a pressure differential between chambers exposed to the piston; and a valve controller which alternately exposes at least one of the chambers to pressure in an annulus surrounding the safety valve, and to pressure greater than that in the annulus. A method of operating a safety valve in a well includes the steps of: opening the safety valve by biasing a piston of the safety valve to displace in response to a pressure differential between a chamber exposed to pressure greater than well pressure, and another chamber exposed to well pressure; and closing the safety valve by exposing both of the chambers to the well pressure.

摘要： Well tools including valves operable by low electrical input. One well tool includes a valve which controls fluid communication between pressure regions in a well, the valve including a rotatable member which is biased to rotate, and a brake or clutch which prevents rotation of the member. Another valve includes a barrier which separates reactants, with the valve being operable in response to the barrier being opened and the reactants thereby reacting with each other. Yet another valve includes a barrier which separates the pressure regions, and a control circuit which heats the barrier to a weakened state. Another valve includes a member displaceable between open and closed positions, a restraining device which resists displacement of the member, and a control device which degrades or deactivates the restraining device and thereby permits the member to displace between its open and closed positions, in response to receipt of a predetermined signal.

摘要： Improved apparatus and methods for deploying tools in multilateral wells are disclosed. Certain ones of the apparatus and methods include a downhole tool centralizer assembly for coupling to a downhole tool. The centralizer assembly has a tubular centralizer retainer with an external surface and an annular recess on the external surface. An annular spring member is disposed within the annular recess, and the annular spring member has an outer diameter greater than a predetermined inner diameter of a bushing disposed proximate a junction between a main wellbore and a lateral wellbore. Other ones of the apparatus and methods include a downhole tool having a substantially identical tubular centralizer retainer and annular spring member. As the centralizer assembly, or the downhole tool, enters the bushing, the annular spring member elastically deforms so that the outer diameter of the spring member becomes substantially equal to the predetermined inner diameter of the bushing. Such elastic deformation prevents the centralizer assembly, or the downhole tool, from accidentally entering the lateral wellbore.

摘要： A decentralizer for a diverter, a centralizing guide bushing and a downhole-deployable locating and orienting subsystem. The subsystem is capable of three modes of operation: (a) a running mode in which an actuating mandrel is in a first axial limit position with respect to a common mandrel, the actuating mandrel placing first and second double-acting springs in a stowed position wherein locating and orienting keys are retracted radially inwardly with respect to the common mandrel to shield the locating and orienting keys from substantial contact with a surrounding well flow conductor as the common mandrel traverses therethrough, (b) a locating mode in which the actuating mandrel is in an intermediate axial position with respect to the common mandrel, the actuating mandrel placing the first and second double-acting springs in a deployed position resiliently to bias the locating and orienting keys radially outwardly with respect to the common mandrel to seek a locating and orienting profile on an inner surface of a surrounding honed bore within the surrounding well flow conductor, and (c) a set mode in which the actuating mandrel is in a second axial limit position with respect to the common mandrel, the actuating mandrel directly engaging and stiffly retaining the locating and orienting keys in engagement with the locating and orienting profile thereby to fix the common mandrel in a desired location and orientation with respect to the honed bore.

摘要： System and method for cementing through a safety valve. A system includes a flow passage, closure mechanism, opening prong repeatedly displaceable to thereby repeatedly operate the closure mechanism open and closed, and a latching device initially maintaining the opening prong positioned isolating the closure mechanism from the flow passage, and releasing the latching device permits the opening prong to open and close the closure mechanism while it is exposed to the flow passage. A method includes the steps of: latching an opening prong so that a closure mechanism is open and is isolated from a flow passage; releasing the opening prong so that the closure mechanism is closed and is exposed to the flow passage; and displacing the opening prong to a position in which the closure mechanism is open and is exposed to the flow passage.
