    摘要： A method and apparatus for controlling fluid flow in a well bore is provided. A base pipe having an outer surface and an inner bore is provided. A first screen jacket is placed therearound. A second screen jacket is positioned adjacent the first screen jacket around the base pipe. An annular space is defined between the outer surface of the base pipe and each screen jacket. A sleeve is disposed between the adjacent screen jackets and an isolated fluid flow path is created between the annular space defined by the first screen jacket and the annular space defined by the second screen jacket.

    摘要： A string for completing a well, the string having several parts including: a base pipe with a hole; a packer in mechanical communication with the base pipe; a screen in mechanical communication with the base pipe, wherein the screen is proximate the hole in the base pipe; an isolation pipe concentric within the base pipe and proximate to the hole in the base pipe, wherein an annulus is defined between the base pipe and the isolation pipe; and an annular flow valve in mechanical communication with the base pipe and the isolation pipe, wherein the annular flow valve controls longitudinal fluid flow through the annulus.
