王瑞平等．判据归类在测井分层中的应用研究．测井技术，１９９５，１９（１）；１６～２１目前，随着测井技术和开采技术的发展，测井资料愈加丰富，而且对储层薄层的要求也越来越高。本文根据多元分析理论，提出在测井分析中采用马哈拉诺比斯（Ｍａｈａｌａｎｏｂｉｓ）距离判据的方法，利用测井资料对地层进行储层划分，以寻求测井资料对渗透层包括薄层的响应。这种方法有别于传统分层方法，具有如下几个特点：①采用多种资料，能够快速寻找到目的层；②采用数学处理方法，排除人为因素影响；③在一定程度上能够补偿测井曲线深度不同产生的误差；④在继承传统曲线基础上，利用了其它曲线资料对渗透层（包括薄层或夹层）进行识别等。应用实例证明这种方法具有一定的理论研究与应用价值。
Recently,with the development of logging and production technology,more and more log data have been obtained. And now,it is much more important to identifythin beds. Application of Mahalanobis distance judgement method to log analysis isproposed on the basis of multivariate statistical analysis theory. Reservoir zonationis made through this method and log responses to permeable zones (thin beds included) are picked out.The above method is different from the traditional one,the advantages of whichare as follows: ①Bed of interest can be found quickly ;②Elimination of manual interference with math method;@Compensation for the depth errors to a certain extent ④ Identification of the permeable zones (including thin beds and interbeds )from other logs.Examples have proved that this method has theoretical and practical values.
