WELL FILTER INSTALLATION METHOD Russian patent published in 2010 - IPC E21B43/08 E21B43/10 

FIELD: mining.

SUBSTANCE: invention related to mining industry, particularly to oil- and gas production and can be used for oil and gas wells development. Well filter installation method includes descending at least of one filter into borehole, the filter installed at bottom part of casing string and includes cuttable plugs. At that install centraliser on every well filter before descending into borehole, centraliser is fixed on well filters pipe vacant of filter itself. Parkers installed over well flirters, their quantity is equal to number of production reservoirs. After the casing string descending wash the borehole and activate parkers alternately from bottom to top, closing central openings in parker's bends with fault element, with ball for example, with the following pressure increase inside the casing string and pumping in cement slurry inside a hole clearance over a production reservoir. After the cement withdrawal execute cementing plugs, parkers bends and fault elements boring, also cut off all of the filter plugs.

EFFECT: process simplification, increase in filter capacity discharge value during oil and gas production.
