Аnnotation: The paper is devoted to evaluation of geomechanical parameters of sedimentary rocks on the basis of empirical expressions found for different kinds of deep borehole logging. Using the data of acoustic logging for Polyarninskoe oil and Aniva gas fields we estimated cohesion and internal friction coefficient. The maximum possible value of horizontal tectonic stresses is determined. The results are applicable to in situ evaluation of stress-strain state of rocks around oil and gas deposits and to construction of their geomechanical models.
