多元统计分析技术在沉积相的研究中得到了广泛的应用。十几年来,随着石油勘探事业的发展,给人们提供了大量的钻孔岩芯资料和实验分析数据,同时也向有关工作者提出了许多问题:如何从一大堆看起来杂乱无章的数据资料中找出沉积物空间分布的规律,对沉积物进行分类和分层,以及确定沉积物的成因等。传统的地学工作在解决这些 Multivariate statistical analysis techniques have been widely used in the study of sedimentary facies. For more than a decade, with the development of petroleum exploration, people have been provided with a large amount of drilling core data and experimental analysis data. At the same time, many questions have been raised to the workers concerned: from a large pile of seemingly disorganized data To find out the law of the spatial distribution of sediments, to classify and stratify sediments, and to determine the causes of sediments. Traditional geosciences work to solve these problems
