FIELD: oil-and-gas industry.
SUBSTANCE: set of invention relates to method of retarding damage of formation exposed surface in gas and oil wells. Proposed method comprises the following steps: string running in borehole extending, at least, partially through barren bed and hydrocarbon strata layer, and retarding the damage of bed exposed surface that includes displacing proppant in borehole along the string so that borehole pressure exceeds the first strata pressure of barren bed, fracture is produced in barren bed, and proppant is transferred in created fracture to make barrier layer to prevent damaging exposed surface.
EFFECT: preventing local destabilization of unstable bed.
