| 摘 要： | 本文阐述的是一种地震岩性反演方法，这种方法是以地震信息为基础，以地质，测井信息作为约束条件，提出一个宽频带的初始波阻抗模型，并使用一种随机迭代算法对初始模型进行修正，以求得一个具有较高分辨率的最终波阻抗模型，此方法与传统的地震岩性反演方法相比较有许多优点，这在本文的理论计算和实际资料处理中得

| Abstract: | This paper ptesents a technique for seismic lithology inversion which constructs an initial brond-band tripedance model based on seismic toformation and constrained by geological and logging information. The initial model is refined with a random iterative algorithm to obtain an ultimate impedance model with high resolution. Theoretical computation and real data processing show that the technique has advantages over conventional seismic lithology inversion techniques. As a result,the ultimate model can be used as a basis for calculation of various strata petroproperties. |
