| 摘 要： | 通过对叠前弹性波阻抗反演及各向异性理论的研究,归纳出一种通过叠前地震数据来预测火山岩裂缝的方法思路:首先引入叠前弹性波阻抗反演,利用其分辨率高的优点来寻找火山岩储层,然后分析裂缝引起的地震波动力学属性随方位角的变化特征,通过各向异性来预测裂缝的方向和发育程度,综合判断火山岩储层裂缝的分布情况。该方法以"面向储层找裂缝"为原则,在分辨率和预测准确性上都有其理论优势,将该思路在试验区域进行尝试,取得了较好的效果。 |
| 关 键 词： | 叠前地震 裂缝 弹性波阻抗反演 火山岩储层 方位各向异性 |

| Abstract: | In recent years,the volcanic reservoir has become a new focus in reservoir prediction.Generally,fractures constitute an important factor of the volcanic reservoir,and volcanic rocks are characterized by variation of spatial distribution and complex internal lithology.Therefore,the detection of fractures in volcanic rocks is considered to be an research challenge.Based on the theory of pre-stack elastic impendence inversion and azimuthal anisotropy,this paper presents an idea for predicting fractures in the ... |
| Keywords: | pre-stack seismic data fracture elastic impendence inversion volcanic reservoir azimuthal anisotropy |
