摘　　要：地层自动对比中常用灰色关联法。论述了该方法的原理及算法。该方法在地层对比中存在某些缺陷,如在关联度匹配分级过程中,一旦某一级匹配与实际情况不吻合,则以后各级的匹配都是错误的,这样,必然会大量地出现地层混乱匹配的现象,造成地层对比结果不准。经过研究及实践,提出2种虚拟关联度的改进方法,其计算结果好于原灰色关联法;同时开发出相应的小层对比软件。The gray correlation method is often used in stratigraphic automatic correlation. Introduced are the method principle and algorithms. But, this method is not good enough for the strata correlation, for example, in the process of matched-graduation of association degree, once a matched-graduation is not agreement with the real formation, the subsequent matched-graduations must be fault, thereby resulting in a wrong strata correlation. Through studying the method and practice, put forward are two virtual association degree algorithms whose calculation results are much better than the above one. And its corresponding slim layer correlation software has been successfully developed.
