In this article, based on the acoustic measurements of core samples obtained from the low to medium porosity and permeability reservoirs in the WXS Depression, the densities and P and S wave velocities of these core samples were obtained. Then based on these data, a series of elastic parameters were computed. From the basic theory and previous pore fluid research results, we derived a new fluid identification...
Typical rock samples with different lithologic characteristics were collected from exploring wells drilled in sandstone-conglomerate sedimental reservoirs with positive rhythm. In different pore fluid states (fully saturated with gas, water and oil), the velocities of compressional and shear waves (Vp, Vs) were measured under different overburden pressure in laboratory. The effects of pore fluid and...
