초록 ▼

A subsurface well flow control system includes a series of movable sleeve type flow control devices installed in a well flow conductor at various fluid-containing fracture zones, and a shifter tool movable through the conductor and operable to selectively shift any selected number of the sleeve portions of the flow control devices, in either direction between their open and closed positions, without removing the tool from the conductor. Radially retractable anchor and shifter key sets are carried in side wall openings of the tool body, and are respectively configured to be lockingly engaged with interior side surface groove sets on the body and movable sleeve portions of any of the flow control devices. The key sets are spring-biased radially outwardly toward extended positions, and an electromechanical drive system disposed within the tool body is operative to radially retract the key sets, and to axially drive the shifter key set toward or away from the anchor key set. This permits the tool to be moved into and through any of the flow control devices in either axial direction, locked to the device, operated to shift its sleeve portion fully or partially in either direction, and then disengaged from the flow control device and moved to any other one of the flow control devices to shift its sleeve portion. Interengaged V-threads on the body and sleeve portions of each flow control device facilitate the releasable retention of the sleeve portion in a partially shifted position.

A method of inspecting well fluid disposed in a subsurface fracture zone through which a well flow conductor extends, the well flow conductor having installed therein, at the fracture zone, a movable sleeve type fluid flow control device the axially movable sleeve portion of which being in a closed position thereof, said method comprising the steps of: providing a shifter tool having: a hollow, general tubular body slidably receivable within and longitudinally movable through the interior of the well flow conductor, said shifter tool body having opposite top and bottom ends, and key means carried on said shifter tool body for driven opposite radial extension and retraction movements relative thereto; mounting an inspection device, such as a logging tool or a video camera, on said bottom end of said shifter tool body for movement therewith through the well flow conductor; inserting said shifter tool, bottom end first into the well flow conductor; moving said shifter tool into the fluid flow control device; drivingly extending said key means radially outwardly into locking engagement with the closed flow control device sleeve portion; axially driving the lockingly engaged key means relative to a portion of said shifter tool body in a manner axially shifting the closed sleeve portion to an open position thereof; drivingly retracting said key means radially inwardly from the shifted sleeve portion to disengage said shifter tool from the opened sleeve portion; raising the disengaged shifter tool within the well flow conductor without removing said shifter tool therefrom; using said inspection device to inspect fracture zone fluid entering the well flow conductor through the opened fluid flow control device; lowering the disengaged shifter tool into the opened flow control device; drivingly extending said key means radially outwardly into locking engagement with the opened sleeve portion; axially driving the lockingly engaged key means relative to a portion of said shifter tool body in a manner axially returning the opened sleeve portion to its closed position; and drivingly retracting said key means radially inwardly from the closed sleeve portion to disengage said shifter tool therefrom.
