人工智能地层分层对比方法研究及应用

On Artificialized intelligence Stratigraphic Correlation Method and Its Application.

人工智能自动分层对比方法是先将测井数字量转化为符号量 ,用计算机模拟手工分层过程实现自动分层 ,再根据已有的分层数据和特征参数 ,按照标志层选择、相似性判断、可能性对比、可信对比、非交叉对比等 5种规则进行地层对比。在大庆油田×区块进行实际应用。对×区块地层连通、砂体尖灭、砂岩透镜体等都能准确地划分对比 ,收效良好。

This method introduced in this paper is to change logging data stream into symbolism, and simulate hand layering by computer to realize automatic layerings, then make stratigraphic correlation through the five rules such as indicated layer selection, comparability judgement, possibility correlation, reliability correlation and noncross correlation according to the known layering data and formation property parameters. This method is applied to × region in Daqing Oilfield and has achieved good results.
