Annotation:
The results of laboratory experiments to determine the anisotropy of the physical and mechanical properties of reservoir rocks at the Chayandinskoye oil and gas condensate field are presented. These properties were studied for core samples, drilled at an angle of 45°, perpendicular and parallel to the bedding. Geomechanical properties were determined by dynamic and static methods. Analysis of the results showed that there are only small deviations in the physical and mechanical characteristics of rocks in these areas. It is concluded that no obvious anisotropy of the elastic and strength properties of the reservoir rocks of the studied horizons has been identified.
