THE NEW METHOD OF STRATIGRAPHIC COLUMNAR SIMULA- TION AND ITS APPLICATION IN SYNTHETIC COLUMNAR SIMULATION OF DETAILED DEPOSITIONAL SECTION

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.
