    摘要： A well screen system for use in a wellbore has an elongate base pipe and a screen encircling the base pipe. The screen is configured to filter against passage of particulate into a center bore of the base pipe. The base pipe has a fluid impermeable portion exterior to the screen. A cover sleeve resides over the fluid impermeable portion of the base pipe. A drain tube with a fluid permeable sidewall resides exterior to the base pipe and screen, affixed to the cover sleeve. The drain tube is adapted to communicate fluid from the wellbore around the fluid impermeable portion to the screen.

    摘要： A gravel packing assembly gravel packs a horizontal borehole. Operators wash down the borehole using an inner string in a first position by flowing fluid from the inner string through the apparatus' toe. Operators then gravel pack by moving the inner string to one or more flow ports between a screen and the toe. Slurry flows into the borehole from the flow ports, and returns from the borehole flow through the screen. The gravel in the slurry can pack the borehole in an alpha-beta wave from toe to heel. In another condition, operators can move the inner string to a second flow port so slurry can flow into the borehole through a shunt extending from the second flow port. When gravel packing is done, operators move the inner string to a port collar in a liner of the assembly to cement the liner in the borehole.

    摘要： Methods and apparatus for completing wells and gravel packing an interval of a wellbore use a perforated shroud (20) having an internal sand screen (21) disposed therein. Particulate material is injected into the annuli between the sand screen and the perforated shroud and the perforated shroud and the wellbore to thereby form packs of particulate material therein to prevent the migration of fines and sand with produced fluids. The perforated shroud has a flow-controlling means for restricting fluid movement between the casing/shroud and shroud/screen annuli during gravel packing.
