摘要
本文提出地层垒积序列的新概念,应用地层垒积序列中岩性百分比、相对重心、相对标准离差3个参数反映地层序列层序结构特征的演化,并应用时间序列分析方法建立这3个结构特征参数的预报方程,在此基础上提出地层柱状模拟的一种新方法。
In this paper the author has put forward the new conception of stratigraphic pilirr-up series. The three parameters of lithologic percentage, relative centre of gravity and relative standard deviation are used to reflect the evolution of sequence structure characteristics in stratigraphic series, and the method of time series analysis is used to construct the predication equations for the three structure characteristics parameters. Based on the above mentioned studies, the author has put forward a new method of stratigraphic columnar simulation. The merit of the new method is as follows: It is suited not only for the stratigraphic columnar of stubborn cycle but also for the stratigraphic columnar of directional evolution; the thick simulation does not rely on the distribution density function. The author An example of applying the new method is introduced to simulate the synthetic columnar for a detailed depositional section.
