TUBULAR PRODUCT AND METHOD FOR PROCESSING FLUID IN WELLBORE Russian patent published in 2016 - IPC E21B43/08 E21B47/00 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions is referred to oil and gas industry and may be used for monitoring and processing of the well medium. Cartridge-type well strainer comprises a cylindrical wall, inner and outer surface, an opening passing to inner space through the cylindrical wall between outer surface and inner surface in order to provide fluid access from outer surface to inner space, material filtering fluid and excluding passage of too large particles through the opening and material of fluid tracer, which is travels through a tubular product placed at the mounting pad at distance from the opening passing to inner space, outside from inner space. The mounting pad is placed so that fluid flow path is limited by limits of passage from the mounting pad at outer surface and through the opening to inner space. The mounting pad is made as a pocket open from the top at outer surface with walls passing downward to the cylindrical wall; it includes closed bottom at the walls base in order to prevent fluid displacing to inner space through the pad.

EFFECT: improved authenticity and efficiency of different areas monitoring in the well; the strainer may be used for processing of fluids in the wellbore.
