摘要
本文提出一种基于地层层序分析的相对深度校正方法:它利用活度分析法将不同次下井测得的两条测井曲线进行地层界面划分;根据地层层序不变的原则利用局部相关分析的方法确定这两条曲线的匹配关系;然后分析这两条曲线各个配对层位的顶、底界面深度,对其中一条曲线进行深度校正。这种深度校正方法计算量小,而且精度较高。
This paper presents an effective method for relative depth correction based on the analysis of strata sequence,in which the activity analysis is be applied to divide correctly sequence boundaries with two different time logs,the matching between the two logs can be determined by partly correlation analysis according to principle of the invariable strata sequence,and then the one depth of the two logs is corrected based on the matching between their interface depths of each layer.This approach has the advantages of less calculated amount and high accuracy.
