FIELD: drilling of oil and gas holes. SUBSTANCE: method can be used for drilling-in of productive reservoirs in conditions of abnormally high reservoir pressure. According to method, in process of drilling, control is maintained of gas inflow to bore-hole. This consists in creation of hydraulic pressure pulses on bottom hole or at bore-hole head and recording signals of pressure in tubes at head of bore-hole and in tube clearance. Equalized condition in bore-hole is maintained by increasing flow rate and/or density of drilling fluid until difference in time in receiving signals of pressure at bore-hole head with regular drilling fluid and in drilling fluid with additives. EFFECT: high efficiency.
