Beschreibung
Zusammenfassung:	A method of increasing the productivity of oil, gas and hydrogeological wells has the steps of performing a slot unloading, providing a cyclical treatment of a near well zone with a formation-treating substance, with a use of cutting slots, determining a region to be treated, selecting a corresponding volume of a treating technological composition, and introducing the volume into a formation to be treated, and subdividing the method into a two stages including a first stage performed by a partial slot unloading of a near well zone so as to remove a main part of support stresses, and a second stage of removing a remaining part of support stresses by a cyclical treatment of the well with a formation-treating substance with control by the density of the rock to be treated and performing a corresponding correction.
