Annotation:
The article evaluates decision-makings for drilling small-diameter wells (SDW) on casing string with a diameter of 102–114 mm. The reduction of the duration of a small-diameter well construction when drilling on a casing string can reach 3,1 days, which is ensured by the exclusion of non-meter types of work (time for geophysical surveys, wellbore drifting and round-trip operations). The proposed procedure is intended, first of all, for drilling small-diameter injection wells (SDW) (without the use of expensive small-sized ESP). The results can be taken into account when developing a domestic complex for the drilling of SDW on small diameter casing strings.
