Abstract of the Disclosure In the disclosed method of successively opening-out and treating formations nozzles are finely pressed against the casing walls in opposition to the selected area of forming a hydraulic fracturing, the nozzle having, each, a through passage of a diameter ensuring that at a constant specified flow rate of a fluid with an abrasive filler through the passage there will be built up a pressure sufficient for hydraulic fracturing of the formation. The abrasive-luden fluid is then pumped through the nozzles at the constant flow rate at a pressure sufficient for making perforation in the casing wall, the pressure being not less thant that required for hydraulic fracturing of the formation, until a perforation of a diameter substantially equal to that of the through passages of the nozzles is formed. With the perforation made, the rate of flow of the fluid with the abrasive filler, pumped through the nozzles, is varied to produce a constant pressure within the bed formation, not less than the pressure required for hydraulic fracturing of this formation.
