新疆棋盘剖面达里约尔组沉积相研究中的马尔可夫链分析

MARKOV CHAIN ANALYSIS FOR STUDYING THE SEDIMENTARY FACIFS OF DALINUEER FORMATION OF XINJIANG QIPAN SECTION

应用马尔可夫链分析,对新疆棋盘剖面上二叠统达里约尔组地层剖面的相序进行了研究。根据微相的转移概率、熵分析和置换分析的结果,总结出了达里约尔组曲流河和辫状河的沉积序列概率模式图,为研究该组的沉积作用和判断沉积环境提供了定量的解释依据。

The Marker chain analysis is used to study the facies sequence of upper Permian Daliyueer Formation in Xinjiang Qipan Section. According to the results of transition probability of microfacies, entropy analysis and substitution analysis, probability patterns of sedimentary sequence of meandering river and braided stream in the said formation are drewn up. The mode charts can be used in explaining iis deposition and sedimentary environment quantitatively.
