摘要
FIELD: oil and gas production.;SUBSTANCE: in barefoot production interval of wellbore there installed is a shank with ready perforated holes inside of which there arranged is a block-type gravel-packed filter of necessary length. Blocks inner space contains porous medium that represents fictitious ground with cubical packing. Fictitious ground consists of detachable elements that represent spherical balls of equal size. The position of detachable elements is rigidly fixed inside the blocks and does not change during wells operation. Block-type filter of necessary length is assembled directly at site and descended to well bottom-hole.;EFFECT: increase of well productivity, reduction of drilling works volumes and cost, increase of service life and reliability of submersible gravel-packed filters.;22 dwg
