Key words: construction, directional and horizontal well, mechanical core
testing, geomechanical model.
The article deals with one of the priority directions of drilling technologies development, i.e. directional and horizontal wells making in offshore fields. Mechanical core testing by dynamic and static methods has been performed for creating a geomechanical model of Yu. Korchagin field with elastic
and strength rock properties determination. The data obtained during
mechanical core testing were used for modelling borehole stability, for
choosing drilling regimes, types of rock destruction tools and developing
drilling liquids composition, and for high-grade tapping of productive beds,
well development and workover
