模拟退火波阻抗反演方法的特点及适用条件

Features and applicable conditions of simulated annealing wave impedance inversion method.

对模拟退火波阻抗反演方法的算法特点、约束条件、适用条件进行了研究,认为该反演方法适用于大时窗、大数据体资料的波阻抗反演,并可用于勘探程度略低、地层结构复杂地区。其特点是人为干预少,地质现象保留客观,反演结果的分辨率和信噪比均有所提高。

Based on the research of the algorithm characteristics, constraint condition and applicable conditions of the simulated annealing wave impedance inversion method, it is considered that this method is applicable to wave impedance inversion with long time window and large data volume, and to the areas with low explorative degree and complex formation structure. The features of this inversion include fewer subjective interference, higher objective remains of geologic phenomena, and the higher resolution and signal to noise ratio of the inversion results.
