AbstractA series of computational rock physics methods to obtain velocity and anisotropic parameters of shale reservoirs have been developed. This series of methods includes numerical modeling of large-scale refined geological models, grid-scale geophysical modeling and determining petrophysical parameters through numerical simulation of seismic waves. The methods proposed in this paper use statistical data of reservoirs rather than measurement data from cores to get varying patterns of reservoir rock physics elastic parameters. Compared to the rock physics method based on core measurement, this method can carefully consider the in homogeneous characteristics of reservoirs, obtain the elastic parameters high related to the size effect which are difficult to acquire by core measuring, and can also avoid the difficulty of obtaining cores with different geological features when getting varying patterns of elastic parameters. In sum, a series of computational rock physical methods have been developed in this work, which provides an effective solution to the problem of large scale geological modeling and computational capacity limitation. Taking the Luojia, Shengli shale reservoir as an example, P wave velocity, S wave velocity and anisotropy parameters of this reservoir varying with TOC content from 3% to 21% are obtained using this series of methods.
