摘要
根据测井资料利用计算机自动识别岩性,是测井数字处理技术急待解决而又比较难的一个问题。本文所介绍的判别岩性的方法是依据人工确定岩性的模式,先用Mahalanobis距离法分层,然后利用概率统计方法区分岩性。该方法经试用,已见到了一定的效果。
Automatic determination of lithology from well logs by computer is a task in log processing technique that needs to be settled A method for determining litholgy is presentedwhich is composed of, first, location of formation by the Mahalanobis's distance methodbased on the model of lithology developed manually and, then, identification of lithologythrough the use of probability statistics. This method was found on trial to be practicable.
