FIELD: oil and gas production.
SUBSTANCE: procedure consists in preparation of suspension of particles of air-blown asphalt in fluid-carrier, in pumping it into well and in forcing it through into bed. High-viscous oil of Mordovo-Karmalskoye deposit is used as fluid-carrier, while weight share of particles of air-blown asphalt in suspension is 5-30%. Also suspension is heated to temperature not less 80°C and forms uniform melt before pumping it into the well. Notably, before pumping melt the well is preliminary filled with hot water of temperature not less 80°C, while thermo-insulated pipes are used as pipes for pumping hot water and melt.
EFFECT: enhanced efficiency of insulating zones of water production in wells.
