Experimental studies into temperature and pressure effect on the quality and fracture of rock samples

Authors: Nikolenko P. V.

Quality of rocks can be affected by many factors. The critical factors are the temperature and stress state. One of the approaches to the in-situ estimation of rock quality is investigation of acoustic properties of rocks, in particular, measurement of Pand S-wave velocities. This article studies dynamics of damage accumulation in limestone samples of different porosity under the action of varied temperatures and pressures. Computer-assisted modeling proves detectability of moment of thermal equilibrium between the faces and center of a sample by flattening of the P-wave velocity curve. The modeling results are compared with the real experimental data. The laboratory-scale tests on a specially designed installation have found that the increasing temperature causes a more intense growth in the amount of damage in porous limestone samples than in less-porous limestone. Alternatively, the increase in the axial pressure reduces intensity of damage process. With increasing axial pressure to 9 MPa, the increment in the amount of damages is reduced in massive and porous limestone by 24% and 48%, respectively, at the temperature being risen from 20 to 100 °С.

Keywords: rock, damage, temperature, pressure, elastic waves, modeling.
