seismic data inversion meaning in English
地震数据反演
Examples
- Firstly , well logging responses of fractured reservoir have been worked out by using rock core to calibrate well logging data . secondly , with the help of the seismic coherence cube , 3d volume visualization , seismic multi - attribute parameter , the curves of geophysical characteristics restructed , seismic data inversion with well logging restrict , the well curves inversion and so on , much work has been done , such as the full 3d seismic data fine structure interpretation and the studies for predicting the fractured reservoir in buried hills . a technique has been invented to predicting the fractured reservoir of metamorphic rock in buried hills with the integration of the multi - attribute and the multi - parameters
利用岩芯标定测井资料，研究了裂缝性储层的测井响应，进而借助于地震相干体技术、三维可视化、地震多属性参数、地球物理特征曲线重构、测井约束地震反演和测井特征曲线反演等多项技术开展了全三维地震构造精细解释和潜山裂缝性储层横向预测研究，形成了多属性、多参数综合预测变质岩裂缝性储层的方法。 - Because the synthetic seismic record and the seismic record data got in the surface are not well matching caused by the dispersion of seismic wave , frequent correction between them must be done before use . under control of well logging data , there are two important methods to get wave impedance from seismic data inversion : wave impedance inversion method based on convolution model and wave impedance inversion method based on wave equation . using seismic data attributes can predict the information of logs
测井资料和地震资料是地震勘探中两种最重要的资料，由于地震波的频散，使合成地震记录与地面地震记录不能完全匹配，因此使用之前必须对二者进行频率校正地震资料在测井资料约束下可以进行反演，以求取地下波阻抗，主要有两种方法：基于褶积模型的波阻抗反演方法和基于波动方程的波阻抗反演方法可以用多属性变换由地震资料预测测井信息。 - The actual data processing indicates that 1 ) compared to conventional wave impedance inversion , the method can improve the resolution of seismic data inversion , 2 ) the fault position in coherent slices of original data and coherent slices of wave impedance are coincide with that in structure maps , but the latter can provide a better criteria for fault interpretation than the former
实际资料应用表明：与常规波阻杭反演相比，该方法可以提高地震资料反演的分辨率：原始地震数据相干体切片和波限抗相干体切片的断层位置均与构造图的断层位置一致，与原始地震数据相干体切片相比，波阻抗相干体切片可为断层解释提供更好的依据。
