APPARATUS FOR TREATING A WELLBORE SCREEN AND METHOD

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.

1. An apparatus for treating a wellbore screen with a coating material, the apparatus comprising: a support for the wellbore screen, the support supporting an outer surface of the wellbore screen and presenting the wellbore screen with open access to its inner bore, as defined by an inner tubular wall of the wellbore screen; an elongate injector for injecting coating material into the inner bore of the wellbore screen, the elongate injector including 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; 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 such that the coating material can be distributed on to the inner tubular wall of the wellbore screen.
