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
