Abstract

Summary

There are presented the results of petrophysical studies of the terrigenous rock samples from the Semyrenkivska area (Dnieper-Donets basin, Ukraine) under high pressures. The set of the studied samples was presented by the Visean sandstones (depth interval 5482ߝ5617 m). All experimental work was carried out at the Petrophysical laboratory of the Geological Department (Taras Shevchenko National University of Kyiv, Ukraine).

The dependences of P-wave velocity and open porosity ratio on the pressure were plotted. The main peculiarities of the void space structure of the rock samples were qualitatively described. P-wave velocity had more significant changes than open porosity ratio for the pressure increase from 0.1 to 60 MPa. The most noticeable changes of both parameters were observed for the pressure increase from 0.1 to 15 MPa and was explained by the changes of the void space structure of rocks. According to the obtained data the samples set was divided into a few groups with the similar behavior under the variable pressure.

The results of the presented investigation will be used for the quantitative assessment of the void space structure of rocks and their reservoir potential prediction.
