Beschreibung
Zusammenfassung:	Method for acid hydro-break of bed prescribes simulation of the process of hydro-break of bed by computer programs, with pumping-in to the well acid solution and pressing liquid under pressure larger than pressure of cracks openings, with shutting the well after the end of pumping pressing liquid, at that the volume and flow rate of acid solution are determined through modeling by computer programs of hydro-break of bed, by pumping acid solution and pressing liquid one provides development of thin vertical crack enough for motion and effect of acid solution in the crack and near it, at that the volume and flow rate at pumping-in pressing liquid one takes not smaller than 1.5 times larger than the volume and flow rate of acid solution, and the well is shutted for the crack closing by quartz grain having separated from the wall of the crack and having moved by it.
