METHOD FOR DETERMINING inhomogeneous elastic and filtration properties of rocks

摘要

1. A method of determining inhomogeneities filtration and elastic properties of the rock, characterized in that cuttings from rock massif cylindrical core samples of various lengths appear through ultrasonic longitudinal P-waves on a regular grid: in multiple directions as the corner, and along the axis of the core sample, and determining elastic speed of longitudinal waves in the dried samples and the saturated liquid obtained dataset elastic velocities of longitudinal waves for both states, which is treated to obtain Func s of the two-dimensional distribution of velocities and their deviations from the mean values ​​for the dried sample and the saturated liquid, represented as a color or monochrome topographic map with contour with a filling between them or without coordinates dihedral angle of observation - height surveillance sensor is compared results obtained velocity measurements in the dried samples and the saturated liquid by calculating a difference value or ratio and the change of the absolute value or a relative deviation sample in a dried state conclude inhomogeneities elastic and filtration properties of the rocks, which is associated with mineral composition, concentration and orientation of fracture disorders with the same mineral composition, then compared to the results of the measurements for samples of the velocity of elastic waves, saturated liquid, and to increase the velocity of the waves compared with those dried samples are judged as to which there are violations in situ rock mass, compared to the results of measurement of elastic wave velocities in
