LEVEL RECOVERY CURVE IN THE RELAXATION THEORY OF FILTRATION O. Yu. Dinariev UDC 532.546 A problem on the level recovery curve in the relaxation theory of filtration is considered when there is a continuous spectrum of internal relaxation times. An asymptotics at large times is found as a functional of a relaxation kernel. An explicit expression with two additional parameters characterizing the relaxation kernel is calculated for a power spectrum of internal relaxation processes in a rock-saturating fluid system.
