FIELD: drilling of soil or rock.
SUBSTANCE: invention relates to drilling wells and may be used to direct a wellbore along a predetermined path. In particular, there is provided a well bore logging tool, comprising: a drill string comprising a bottom hole assembly (BHA) with sensors configured to obtain actual deformation measurement results and bending moment depending on the location of the BHA, in the intervals on the BHA, located at a distance from each other; data processing system configured to sample said actual measurement results and operationally generate a wellbore curvature log; and a user interface configured to display a wellbore curvature log. With the help of the data processing system, a method of forming a well log is realized by: providing a calculated wellbore trajectory; obtaining predicted results of deformation and bending moment measurements on the basis of the calculated wellbore trajectory; the determining the error between the predicted measurement results and the actual measurement results; updating the calculated wellbore trajectory to reduce the error; repeating said acquisition, determining and updating to refine the calculated wellbore trajectory; and transforming the calculated wellbore trajectory into a well log borehole log.
EFFECT: technical result is the expansion of the arsenal of technical means for drilling wells along a given trajectory.
