【 摘 要 】

The storage spaces of Karsts carbonate reservoir are characterized as heterogeneity. Due to low signal to noise ratio, seismic inversion using partially stacked data is often used to characterize the carbonate reservoir. A physical model is used to analyze influence of seismic inversion on heterogeneity. On the one hand, the difference in lateral resolution is quantitatively studied. On the other hand, the influence of noise on the lateral resolution in seismic inversion is discussed by adding random noise of different degree. The results demonstrate that the signal to noise ratio can be improved by seismic inversion while the lateral resolution is reduced subsequently. Additionally, random noise influences the lateral resolution, that is, the inverted volume of heterogeneity become smaller as the noise increased.
