The article describes the issue of determining the properties of rocks with different fluid saturation and the relationship between changes in these properties from the stage of oil field development. The mineral composition of the studied clayey samples of oil reservoir rocks was given. The process of changes in the strength and elastic properties of the rock due to different saturation with kerosene and water was described. The dependences of the ultimate strength under uniaxial compression, elastic modulus and Poisson's ratio for rocks of different fluid saturation were presented. The decrease in the strength and elastic modulus of rock samples with complete replacement of kerosene with water reached 15-20%, and in comparison with the results obtained for a sample in an air-dry state, the decrease in these same properties reached 30-40%. Based on the theoretical and practical studies the need to determine the strength and elastic properties of rocks depending on saturation in real field conditions became obvious.
