The results of the analysis of the connection between capillary pressure curves and acoustic properties in samples of sedimentary rocks are presented in this paper. The collection of sedimentary reservoir rocks consisting of 8 samples was analyzed. Investigation included determination of density, porosity and permeability, electrical resistivity, and velocities of elastic waves. Capillarometric studies using a centrifuge have been performed. The research showed that capillary pressure curves provide valuable information on pore size distribution and allow determining the contribution of free and combined water in cavities. Joint analysis of capillary curves and graphs of changes in the velocities of elastic waves at centrifugation allows us to more fully understand the processes of propagation of elastic waves in a multicomponent environment and to specify models of reservoir rocks.
