%X Continuous imbibition and dehydrating experiments are carried out for six samples in laboratory. Compressional wave velocity (V P) and shear wave velocity (V S),the imbibition's and dehydrating rate with water saturation are measured during the two processes. The influence of pore fluid on rock elastic properties at low saturation is analyzed. The experiments show that different saturation process leads to different velocity-saturation relationship. The velocities are not only related to water saturation,but also related to pore fluid distribution during different saturation stage. The velocities are also related to the physical and chemical interaction between water and rock skeleton.
