Y2K Tutorial Fundamentals of seismic rock physics

摘要

Although rocks are extremely complicated, their seismic properties(V_p, V_s, and impedance) depend largely on a com- bination of connectivity and elasticity and density of what is connected. As a result, many rules of thumb can be explained by such combinations. For example, dolomite has a high bulk modulus and the individual "grains" are well connected in a dolomite rock, so that compressional velocity and impedance are high.
