摘要： A method of drilling a wellbore includes drilling the wellbore through a formation by injecting drilling fluid through a drill string and rotating a drill bit. The drill string includes a shifting tool, a receiver in communication with the shifting tool, and the drill bit. The method further includes retrieving the drill string from the wellbore through a casing string until the shifting tool reaches an actuator. The casing string includes an isolation valve in an open position and the actuator. The method further includes sending a wireless instruction signal to the receiver. The shifting tool engages the actuator in response to the receiver receiving the instruction signal. The method further includes operating the actuator using the engaged shifting tool, thereby closing the isolation valve and isolating the formation from an upper portion of the wellbore.

摘要： A fluid flow control system for downhole use in an oil or gas well has a choke with a conduit having an inlet and an outlet, and a flow restrictor comprising first and second choke members 10,20, one of which rotates relative to the other to choke or promote flow. The first and second choke members 10,20 are axially spaced from one another, and have mating faces that are optionally planar, and are axially stacked in the choke. The choke is operated by a shifting tool 50, which grips the inner surface of the rotating choke member 10, and rotates it relative to the other 20, in order to vary the flow. The shifting tool 50 is adapted to be deployed on a line or string of tools passing through the bore of the choke.

摘要： A bidirectional downhole fluid flow control system is operable to control the inflow of formation fluids and the outflow of injection fluids. The system includes at least one injection flow control component 112 and at least one production flow control component 114 in parallel with the at least one injection flow control component 112. The at least one injection flow control component 112 and the at least one production flow control component 114 each have direction dependent flow resistance, such that injection fluid flow experiences a greater flow resistance through the at least one production flow control component 114 than through the at least one injection flow control component 112 and such that production fluid flow experiences a greater flow resistance through the at least one injection flow control component 112 than through the at least one production flow control component 114.

摘要： A valve assembly for regulating fluid flow in a horizontal wellbore. A housing can be coupled to a production tubular. A chamber is defined within the housing and can be in fluid communication through a flow channel with an inner annulus formed adjacent the wellbore. A piston and a biasing member can be disposed within the chamber, where the biasing member biases the piston into a first position. A flowpath is defined within the housing and communicable with both the production tubular and the inner annulus. The flowpath can include one or more nozzles disposed therein, and the piston can be configured to move between the first position allowing fluid flow through the flowpath to the production tubular and a second position preventing fluid flow to the production tubular.
