Аннотация
Effects of fluid-saturation variations on the acoustic parameters of reservoir rocks under simulated formation conditions are studied. Experimental velocities of ultrasonic waves traversing cores saturated with CO2, formation water, and crude oil are measured at various temperatures and pressures and analyzed. Experimental results showed that the velocities of longitudinal and transverse waves in cores increased if the confining pressure and rock elasticity modulus increased. The transverse wave velocity did not depend on the saturating substance. The longitudinal wave velocity was greater for water saturation than for CO2 and oil saturation.
