摘要： Casing valves for selective well stimulation and control. A well system includes at least one valve interconnected in a casing string operable via at least one line external to the casing string to selectively control fluid flow between an exterior and interior of the casing string, and the casing string, valve and line being cemented in a wellbore. A method of selectively stimulating a subterranean formation includes: positioning a casing string in a wellbore, the casing string including spaced apart valves operable via a line to selectively control fluid flow between an interior and exterior of the casing string; and for each of multiple intervals of the formation in sequence, stimulating the interval by opening a corresponding one of the valves, closing the remainder of the valves, and flowing a stimulation fluid from the casing string into the interval.

摘要： A method of selectively actuating well tools includes the steps of: selecting a well tool for actuation by current flow in one direction through a set of conductors; and selecting another well tool for actuation by opposite current flow through the set of conductors. A system includes multiple control devices that control which well tool is selected for actuation in response to current flow in at least one conductor set. A current direction in the conductors selects a certain well tool for actuation. A method of using n conductors to selectively actuate n*(n−1) well tools includes the steps of: arranging the conductors into n*(n−1)/2 sets; connecting the conductor sets to respective groups of the well tools; and controlling direction of current flow through at least one of the sets of conductors, thereby selecting at least one well tool in the respective group of the well tools for actuation.

摘要： A flow regulator for use in a subterranean well. A well flow regulating system includes a flow regulator for regulating a flow rate of a fluid in a wellbore, the flow rate remaining substantially constant while a differential pressure across the flow regulator varies. The flow regulator is adjustable while positioned within the wellbore to change the flow rate. Another well flow regulating system includes a flow regulator for maintaining a desired fluid flow rate between an annulus and an interior passage of a tubular string. The flow regulator includes a closure device, a biasing device which applies a biasing force to the closure device, and a flow restriction which operates to apply a restriction force to the closure device. The biasing force and/or the restriction force is adjustable downhole to change the flow rate.
