摘　　要：探索小层对比定量分析方法与手段,弥补传统人工小层对比定性分析的不足,确保构造建模的正确性。将小层对比作为一个灰色系统研究,模拟人脑和创造性思维的对比过程,借助于数学方法,开展井间灰色关联分析,以关联度作为定量分析的标准,建立数学算子与地质解释的对应关系。结果表明,该方法不仅可以较准确地实现井间定量化自动连层,还可以对人工小层划分结果进行定量化检测,识别异常小层划分。This paper explores the method and means of quantitative analysis about correlation of small layers to compensate the lack of the conventional and artificial correlation of small layers and make sure of the validity of the structure modelling.This paper researches the correlation of small layer by taking it as a grey system,simulates the human brain and creative thinking,applies the mathematical methods to conduct grey relational analysis,and uses the association degree as the quantitative analysis standard to establish the corresponding relation between mathematical operators and geological interpretation.The result shows that this method can realize the automatic connection of small layers quantitatively and prepare for the structure modelling better,and can detect the results of the division and correlation of small layers by hand and exclude abnormal small layers division.
