FIELD: oil and gas industry.
SUBSTANCE: invention relates to oil and gas industry, in particular, to insulation of fluid inflows into oil and gas wells during operation. Method for insulation of fluid-saturated formations of production thickness of production wells includes extraction of water-saturated formation interval, injection of insulating material into bottom-hole and near-well zones of water-saturated formation using water jet streamtubes, wherein injection is performed prior to running-in of production string by drilling of side inclined shaft, by means of repeated opening of productive stratum not developed with development with simultaneous hydromechanical hardening by water jets streamtubes of insulating material, in form of gel-cement drilling solution, in modes of synchronous and coordinated effect of mechanisms of quantum hardening of well shaft with formation of near-well screen during 0.007–0.015 s with further development and introduction of well into operation by open face.
EFFECT: technical result is improvement of quality and efficiency of isolation of fluid saturated formations of productive stratum.
