地震层状构造理论与地震模型——Ⅰ.理论评述

SEISMIC MODEL OF LAYER STRUCTURE AND ITS THEORY

本文从地震层状构造理论观点讨论了地震勘探解释及其数字处理中所采用模型的性质,指出,目前作为数字处理技术、反褶积及拟测井技术等等方法之基础的线性模型与客观实际之间存在严重矛盾,难以满足要求日益精密之岩性勘探与解释的需要.根据地震层状构造理论,进一步讨论了非线性模型的物理合理性、导出了描述其传播特性的传递矩阵,并阐述了与此有关的若干重要解释问题.

This paper deals with the properties of seismic model being used in the interpretation and digital processing of data from the view point of layer structure. In this paper, the author pointed out that the linear model which is taken as the basis of digital processing, deconvolution as well as the pseudo velocity log up to now, is in contradiction with the objective reality and is hardly to meet the requiremets of lithologic exploration and its interpretation. In view of the above mentioned facts, he put forward a nonlinear model and proved it to be more close to the actual situation. In order to describe the nature of the model precisely, he worked out a transitive matrix and solved a series of key problems related to the application of this model.
