FIELD: oil and gas production.
SUBSTANCE: method consists in drilling vertical section of well and successive drilling of interval up to bottomhole. The feature of the method is drilling of single profile step-less section along trajectory after drilling of vertical section; horizontal and vertical points of trajectory are determined from mathematic formula with consideration of linear scale factor, inclination angle and friction ratio.
EFFECT: reduced power expenditures and time of construction of directional well due to reduced resistance to movement of drilling string and inter-well equipment along trajectory determined from given ratio.
