| 摘 要： | 随机反演突破了地震频带宽度的限制，可获得高分辨率的地层波阻抗资料，具有纵向分辨率较高且不完全受井分布控制等优点。随机地震反演不仅可以获得高分辨率波阻抗资料，还可以得到伽玛、孔隙度等储层物性参数，具有更直接的岩石物理意义。实例应用表明，利用该方法得到的反演结果精度更高，储层预测效果更好。

| Abstract: | High vertical resolution impedance can be obtained by seismic stochastic inversion which is not limited by the bandwidth of seismic data. Through stochastic inversion, not only the high resolution impedance, but also the gamma ray, porosity and other lithologic parameters with physical properties of rock can be inverted. Real case application indicated that reservoir prediction results with higher precision could be acquired using the approach of seismic stochastic inversion. |
