FIELD: process engineering.
SUBSTANCE: proposed method can be used in producing hydrocarbons when flow channel represents case pipe or well liner, while underground reservoir makes flow source. Method comprises shutting off at least a part of source or preselected place by temporary cover, creating degradable barrier between the hole in reservoir and aforesaid temporary cover, forming passage around aforesaid barrier between the hole and source, allowing the barrier to degrade to form at least of degradation product and removing temporary cover by aforesaid product at the former location of degradable barrier. Invention pertains also to method of temporary shitting off mechanism in extracting hydrocarbons and temporary protection of well filtration means. Invention is developed in invention claims.
EFFECT: temporary shutting off of flow, along with unobstructed removal of degradable barrier.
