| 摘 要： | 该文介绍了在弱各向异性条件下,基于Thomsen裂缝理论——HTI介质各向异性参数的转换波近似反射系数公式,通过AVO正演,比较分析各向异性系数对于P-SV波反射系数的影响及对P-P波反射系数的影响。结果表明,应用联合P-P波和P-SV波的数据进行联合反演,能够更好地降低数据结果的不唯一性,从而得到更精确的裂缝参数。

| Abstract: | Based on Thomsen fracture theory,the converted wave approximate reflection coefficient of in weak aniso-tropic 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-SV wave data to carry out inversion can get more accurate fracture parameters. |
