摘      要：Laboratory experiments were conducted to measure the compressional wave velocities under hydrostatic pressure in Shirahama Tako sandstones with a porosity of 12% and 24%,*** dry samples,the pressure dependence of velocity is ascribed to the difference in pore *** were also measured to map the movement of the injected CO2 within water-saturated samples during CO2 *** the water-saturated samples,velocity changes caused by the CO2 injection are typically on the order of 10%.A series of seismic tomography experiments are conducted on porous sandstone samples to demonstrate the use of cross-well seismic profiling for monitoring the migration of CO2 in geological sequestration projects.
