Carbonate deposits in the area of the Sakhalin Island are underanalyzed. It is necessary to undertake a deeper examination of properties of carbonate rocks in Sakhalin, in particular, their physical and mechanical properties. The article presents the small-scale geomechanical testing data on carbonate rocks samples from three deposits: Gomon, Lisie and Bely Kamen. Sakhalin’s carbonate rock strata adjoin the Mesozoic clay terrigenous and volcanic siliceous formations. The mechanical properties of the samples appeared to be rather similar and were analyzed jointly therefore. Their key characteristics were systematized, the correlation dependences on the acoustic wave velocities were plotted, and their dynamic and static characteristics were compared. The P/S wave velocity ratio is found to be 1.84 on the average, which complies with the average data around the world. The correlation dependences of the geomechanical characteristics of the test rocks on the velocity of P-wave are obtained. They are mostly linear. The correlation of the uniaxial compression strength of the test rocks with the P-wave velocity is presented. The results are satisfactorily described by the linear approximation at a confidence of 0.54.
The authors express their gratitude to engineers of IMGG’s Shared Use Center V. V. Zhurbenko, A. R. Lukmanov and Yu. V. Kostrov, as well as to Researcher of IMGG V. S. Zarochintsev for the help in core sampling and sample preparation.
