摘要： There is provided a wellbore screen having a base pipe and a strip of filter medium wrapped around the base pipe. The strip of filter medium includes one or more layers of woven steel mesh of various weave patterns, fibers sizes, and/or thread tensions. During the construction of the screen, the strip is wrapped around the base pipe under high tension. The strip has two lengthwise edges that may overlap to form a bonded interface.

摘要： An apparatus and methods for applying an inner coating to a wellbore screen are described. The apparatus comprises a support for the wellbore screen, an elongate injector for injecting coating material into the inner bore of the wellbore screen, and a driver for positioning the elongate injector into the inner bore and moving the elongate injector through the inner bore to introduce coating material to the inner bore. The elongate injector has a supported end, a distal end, and a coating material delivery line extending through the elongate injector from a coating material supply to a port at the distal end.
