对弱各向异性条件下HTI介质中P-SV波近似线性反射系数公式,引入常用的等效Thomsen各向异性参数并进行了推导,得到了更为简单实用的反射系数近似公式,并对其AVO属性进行了正演模拟研究。
The approximate linear reflection coefficient formula of P-SV wave in HTI medium with weak anisotropy is introduced, and the commonly used equivalent Thomsen anisotropy parameters are introduced and deduced. A more simple and practical approximate formula of reflection coefficient is obtained, AVO attribute forward modeling study.
