lithologic layering meaning in Chinese

岩性层理

The mathematical statistics method and extrema variance clustering method can be used to visible automatic classifying and reading of logging curves . the lithofacies classifying program basing on multi - mineral model analysis presents a new method to analyze logging - facies and more accuracy and visualized logging facies section can be reached by using this method . in addition , it supplies reliable lithologic layering reference for search and evaluation of oil / gas caprock and it also made up for the high cost of core - drilling and the inaccuration between lithic fragment description and depth
采用基于“数理统计-极值方差聚类法”的面向对象可视化操作方法可有效地解决测井曲线的可视化自动分层取值问题；而基于多矿物模型分析的岩相划分程序又提供了一种新的测井相分析方法，能得到更为准确直观的测井相剖面，为寻找和评价油气盖层提供了可靠的岩性分层依据，同时弥补了钻井取心费用高和录井岩屑描述与深度有误差的缺陷。
