FIELD: soil or rock drilling; mining.
SUBSTANCE: invention relates to underground drilling, and more specifically to control of directional well drilling and computing devices used in such drilling. Method comprises arranging a drill string in a wellbore; wherein the drill string comprises a drill string bottom assembly (DSBA) comprising a steering device, one or more sensors sensitive to one or more formation properties, and one or more sensors sensitive to DSBA current orientation in borehole. Said method also includes obtaining information relating to formation properties from DSBA and information relating to current orientation of DSBA in well bore; processing said information using a programmable optical computing device, which is either a programmable optical computing device or a quantum computing device. Computing device calculates position of formation elements relative to current position of borehole in real time and compares current position with preset path.
EFFECT: technical result is creation in real time of more realistic two- and three-dimensional models of formation with possibility of improving geosteering during drilling of essentially horizontal wells in order to maintain greater well centring within productive zone.
