Abstract

Based on Thomsen fracture theory, the converted wave approximate reflection coefficient of in weak anisotropic HTI media is introduced. Through AVO forward modeling, the influences of the anisotropy coefficient on P- SV wave reflection coefficient and P- P wave approximate reflection coefficient are analyzed and compared. The result shows that combining P- P wave and P- SVwave data to carry out inversion can get more accurate fracture parameters.

Key words： in-situ stress; logging data; rock mechanics parameter; fractured testing; core testing
