FIELD: oil industry.
SUBSTANCE: invention relates to a method for designing and controlling the profile parameters of a directional well. The profile of a directional well includes straight and curved sections made along a clothoid with a continuously changing curvature. The construction of a profile of a curved section with a continuously changing radius of curvature is carried out using a linear mathematical relationship that links the variable parameters of the wellbore trajectory. To build a profile, the following variable parameters of the wellbore trajectory are used: the depth of the curved section, the deviation from the vertical, and the zenith angle corresponding to the inclination of the profile tangent to the vertical axis.
EFFECT: simplification of preliminary calculations of the trajectory of a directional well, the possibility of operational control of the profile parameters in the process of drilling a well.
