二维横向各同同性介质中VSP三分量地震记录合成
3-COMPONENT VSP DATA MODELLING IN 2-D TRANSVERSELY ISOTROPIC MEDIA
【摘要】 本文作者利用快速傅里叶变换(FFT)技术的快速与高精度等优越性,对2-D横向各向同性介质中VSP三分量地震记录U_x、U_y与U_z的合成进行了研究,实现了快速三分量地震记录正演新算法。理论模型计算结果表明横向各向同性介质中横波分裂现象的存在,并说明了这项数字仿真技术的可行性。
【Abstract】 The authors take the advantage of the rapidity and the high precision of FFT in modelling 3-component VSP data ( Ux , Uy and Uz ) for 2-D transversely isotropic media. As a result, a new fast algorithm is developed for 3-component VSP data forward modelling. The computing results have revealed the presence of shear-wave splitting in transversely isotropic media and confirmed the feasibility of the numeric modelling method.
