FIELD: oil and gas industry.
SUBSTANCE: method involves determination of inflow of hydrocarbons into a well bore, determination of reduction of rate of hydrocarbons inflow, switch of control of outlet from a well bore for maintaining selected pressure in the well bore to control of rate of fluid outlet from the well bore to ensure its constant rate, if it drops, return of control of outlet from the well bore for maintaining selected pressure, when inflow of hydrocarbons into the well bore is at the acceptable level.
EFFECT: increased efficiency of drilling through a bed with limited volume of hydrocarbons.
