摘要： The present invention provides a fluid flow control device for controlling the formation fluid flow rates through a production string. The device includes a generally tubular body for placement into the wellbore. The tubular body has a screen at an outer surface for preventing sand from entering into tabular body. The fluid flowing through the screen passes through a labyrinth. A slidable sleeve on the labyrinth controls the fluid velocity there through. The slidable sleeve screen is moved by an electrically-operated device, such as a motor paced in the production string. The fluid leaving the labyrinth passes to a tubing in the tubular body for carrying the fluid to the surface. The flow control device further may include a control circuit in the production string for controlling the operation of the electrically-operated device. The control circuit may communicate with the a surface control unit, preferably a computer-based system, which may provide commands to the downhole control circuit for causing the electrically-operated device to adjust the position of the sleeve. The sleeve may be positioned at any place on the labyrinth, providing accurate control over the flow rate. The surface control unit may communicate with the downhole control circuit via a data communication link, which may be a cable or a trans/receiver system.

摘要： Several downhole flow control devices are disclosed which are meterable and are also capable of shutting of a particular zone in a well. The several embodiments include a multiple valve body, a toroidal inflatable valve, and a series of related choke systems. The downhole flow control choke mechanisms each include a downhole electronics package to provide programming or decision making capacity as well as motor actuation systems. Each choke mechanism also includes a system whereby the device can be converted to manual operation and actuated by a conventional shifting tool.

摘要： A casing is provided with a sealable shifting sleeve. A whipstock is insertable into the casing and may be supported off of the casing in a predetermined location so that it is oriented toward an open window in the casing when the shifting sleeve is selectively moved upwardly. By presenting an open window for the whipstock oriented toward the window, a drillbit may be lowered through the casing to interact with the whipstock to immediately begin the drilling of the deviated wellbore. The drillbit cuts through any cement, if present, and into the formation. A bore is presented in the whipstock to allow production from pay zones below the whipstock while it is in place. Should it become necessary, the sliding sleeve may be subsequently closed to isolate the deviated wellbore which has been drilled with the whipstock through the open window.
