地震不连续点成像
|
摘要
地震不连续点成像类似于反射波勘探中的共中心点叠加技术.它是根据绕射波的运动学和运力学两方面特征，在共炮间距道集上，将绕射波聚焦成像，形成绕射点剖面。该绕射点在其剖面上以亮点的形式显示出来，它有可能与断点相对应。应用该绕射点剖面与原地震剖面进行叠合，有助于解释人员对断点进行定位解释。
The image of seismic discontinuous points is analogous to CMP stacking technique in reflection wave exploration. The technique produces diffraction point sectionby focusing and imaging the diffraction waves in common-offset gathers according tothe kinetic and dynamic characteristics of the diffraction waves- Diffraction pointsappear as bright spots in such sections, they may correspond to fault points. Thecombination of diffraction point section with the corresponding seismic sectionfavours interpreter's fault point interpretation.
