	Productive strata opening method at drawdown Invention is referred to the area of oil and gas industry, and namely to methods of producing horizons opening by wells. The method includes running in of drill pipes with a drilling bit and containers with pressure gages to the well. Upon the hole cleaning surveys are made in order to set drilling modes at drawdown, thereafter upon beginning of flushing liquid circulation with a gaseous agent at least three drawdown-generating modes are made for delivery of the aerated flushing fluid. At all modes values of pressure are measured, time is recorded and pressure losses are identified within the interval from the pressure gage installation site up to the wellhead.
