    摘要： A flow control system for use in a subterranean well can include a flow chamber through which a fluid composition flows, and a plug which is released in response to an increase in a ratio of undesired fluid to desired fluid in the fluid composition. Another flow control system can include a flow chamber through which a fluid composition flows, a plug, and a structure which supports the plug, but which releases the plug in response to degrading of the structure by the fluid composition. Yet another flow control system can include a flow chamber through which a fluid composition flows, and a plug which is released in response to an increase in a velocity of the fluid composition in the flow chamber.

    摘要： Apparatus and methods for controlling the flow of fluid, such as formation fluid, through an oilfield tubular positioned in a wellbore extending through a subterranean formation. Fluid flow is autonomously controlled in response to change in a fluid flow characteristic, such as density or viscosity. In one embodiment, a fluid diverter is movable between an open and closed position in response to fluid density change and operable to restrict fluid flow through a valve assembly inlet. The diverter can be pivotable, rotatable or otherwise movable in response to the fluid density change. In one embodiment, the diverter is operable to control a fluid flow ratio through two valve inlets. The fluid flow ratio is used to operate a valve member to restrict fluid flow through the valve.

    摘要： A well screen inflow control device with check valve flow controls. A well screen assembly includes a filter portion and a flow control device which varies a resistance to flow of fluid in response to a change in velocity of the fluid. Another well screen assembly includes a filter portion and a flow resistance device which decreases a resistance to flow of fluid in response to a predetermined stimulus applied from a remote location. Yet another well screen assembly includes a filter portion and a valve including an actuator having a piston which displaces in response to a pressure differential to thereby selectively permit and prevent flow of fluid through the valve.

    摘要： An apparatus is described for controlling flow of fluid in a subterranean formation based on a selected characteristic of fluid flow, such as viscosity, velocity or density, as that characteristic varies over time. A pathway-dependent resistance assembly, such as a vortex chamber having two inlets and an outlet, provides varying resistance to fluid flow based on the ratio of flow from the inlets, the direction of flow as directed by the inlets, and the characteristic of the fluid. The incoming flow ratio is preferably determined by flowing fluid through a plurality of passageways having differing flow rate responses to fluid having differing characteristics. Fluid of a selected characteristic will encounter lesser resistance to flow across the system, while fluid of an un-favored characteristic will encounter greater resistance to flow. Thus, flow of well fluids can be autonomously restricted as the fluid characteristics change over time.

    摘要： A method of completing a subterranean well and associated apparatus therefor provide efficient operation and convenience in completions where production of fluids from a lateral wellbore and a parent wellbore is desired. In one disclosed embodiment, the invention provides an efficient method of protecting a junction of multiple wellbore portions by positioning a tubular drilling guide within the well extending through the junction. In one aspect of the present invention, the drilling guide is sealingly engaged with certain ones of the wellbore portions while drilling operations are being performed.
