Zusammenfassung:	Method for insulation of absorbing layer with abnormally low stratal pressure includes pumping-in to the well with static liquid level placed lower than the mouth of the well of plugging agent and pressing liquid. Experimentally one determines minimal pressure P1, at which liquid being in the well is pressed to the bed, and maximal pressure P2, at which the plugging agent chosen does not go to the bed. After that one pumps in to the well portions of plugging agent and pressing liquid forming hydrostatic pressure P determined by formula. One pumps in to the well one portion of plugging agent only, with column height hm., and at P1>P2 one pumps in to the well in sequence calculated column heights of plugging agent needed for insulation of absorbing bed in given well interval, at that calculation and pump-in of each next portion of column height is performed after repetitive determination of P1 and P2.
