FIELD: oil and gas industry.
SUBSTANCE: group of inventions relates to the field of oil production. System using the casing during drilling comprises casing string, which comprises upper latching device and lower latching device, and fixed in the lower latching device the bottom hole assembly (BHA) for directional drilling. At that, the BHA is configured to locking into the upper latching device to increase the guide hole. BHA can be moved either from the upper latching device to the lower latching device or from the lower latching device to the upper latching device, wherein in both cases without exiting the wellbore.
EFFECT: providing with the BHA easy and functional manipulation during drilling.
