Abstract:
?两组任意夹角的倾斜裂缝在自然界中具有普遍性,本文针对两组任意夹角的倾斜裂缝介质模型,采用交错网格高阶差分法进行地震波场二维三分量数值模拟。根据hudson理论和bond矩阵变换得到裂缝型储层在观测坐标下的弹性系数,对比了在本构坐标和观测坐标下地震波场之间的差异,分析了不同方位角下炮记录波场特征、不同炮检距方位角道集上的波场特征,以及改变裂缝夹角后在方位角道集记录上的响应特征。研究表明,裂缝型储层的各向异性特征是裂缝的综合反映,各向异性的强弱不仅与裂缝的发育强度有关,还与裂缝发育的复杂程度有关。通过对方位各向异性介质数值模拟和波场特征的分析,可为方位各向异性介质的裂缝反演提供理论基础。
