Abstract
The invention can be used for the oil and gas production, more specifically to the completion of oil and gas wells. The inventive method consists in mechanically perforating the wall of a casing pipe and supplying a working agent in a formation through a perforated hole. A knurling roller provided with a shear circulation valve which has additional wash ports is used as a cutting tool. Said method extends the technological capabilities for acting on the productive formation of a bottom-hole zone, i.e. makes it possible to carry out the swabbing (compressing), acid treatment and the hydraulic fracturing of the formation at a high efficiency and without additional round-trip operations of a perforator.
