The buried hills of the Archean metamorphic rocks in Bozhong Depression Bohai Bay Basin are main gas-bearing strata, with burial depths ranging from 4000 m to 5500 m. However, have internal structural characteristics, such as diverse mineral components, oriented arrangement particles, complex pore connectivity, variable crystal structures, orthogonal development multiple sets fractures, and uneven fluid filling. Compared conventional reservoirs, they obvious heterogeneity anisotropy characteristics. Traditional rock physics modeling methods no longer suitable for predicting elastic anisotropic parameters reservoirs. Therefore, we introduced a vector mixed random medium model calculate effect minerals on modulus matrix factor describe impact recrystallization alteration metasomatism matrix. Practical applications shown that new, improved method can better estimate S-wave velocity wells compared traditional methods, providing reliable basis fractured reservoirs at hills.
