摘要
The critical porosity and relative elastic parameters of the porous media are usually studied by methods of experimental measurements and data analysis. So in this paper, a numerical calculation approach and some equations of bidirectional linear regression are provided for calculating these elastic parameters. Correlation coefficients of simulated data and measured data are over 90%, which proves the feasibility of the equations and the availability of this method. In the field of oil and gas exploration, the method can be directly used to calculate elastic parameters of pore fluid, and plays a crucial role in predicating oil and gas reservoirs.
