减弱地质数据丛聚效应的方法——以新疆油田为例

How to Reduce the Clustering Effect of Geologic Data－an example from Xinjiang oilfield．

为了得到一个能有效代表整个研究区内地质数据的分布特征，需要对丛聚在一起的地质数据分配较小的权值，而给稀疏分布的地质数据赋予较大的权值。本文介绍了C．Deutsch提出的一种减弱地质数据丛聚效应的方法——Cell Declustering 方法，并给出了一个在新疆油田中应用的实例。

 In order to effectively represent the distribution features of geologic data it is necessary to allocate asmaller value of weight for dense clustering data while allocate a bigger value of weight for sparse clustering data． Thispaper recommends a method the Cell Declustering method which has been suggested by C． Deutsch to decrease the clustering effect of geologic data and gives an example for its application in Xinjiang oilfield．
