FIELD: oil and gas production.
SUBSTANCE: procedure for performing operations of cleaning borehole of well consists in preparation and introduction of water fluid containing sphinganic hetero-poly-saccharide into well borehole, in carry-over of material filling well borehole in water fluid, in extraction of at least part of fluid and carried over material filling borehole on surface for in essence separation of material filling borehole from fluid and in introduction of given part of fluid into borehole for second cycle not requiring considerable replenishment with sphinganic hetero-poly-saccharide. The procedure can be used at drilling, exposing, substitution, repair, well completion, maintenance, testing, well killing, hydraulic break and in filling with packer liquid.
EFFECT: raised resistance to shear destruction.
