 孤岛油田馆6 砂组油藏属岩性构造层状油藏，储层非均质性强，油水关系复杂。文中总结了利用测井参数交会图法、测井多信息多元统计法和灰色理论判别分析方法识别油
水层的方法原理，制定出了相应的油水层判别标准，在孤岛油田馆6 砂组得到了很好地应用，其结论与实际资料相一致。

The reservoirs in sixth sands of Guantao Formation,
Gudao oilfield, is a lithologic-structure layered oil pool. The
reservoir heterogeneity is serious, and the relation of oil and
water is complicate. Since Gudao Oilfield came into the stage
of high water cut, the oil layer is waterflooded seriously, the
remaining oil is scattered, and hence the research of the
reservoir discrimination as an important content of reservoir
description becomes more and more important. This article
summarized the methods and principle of identifying oil
reservoirs by the methods of log parameter cross-plot, logging
information multivariate statistics and grey theory
discriminatory analysis, and draw up the standard of oil
reservoir discrimination .The result of application is basically
conformed to that of well testing result, the methods have a
great potential of application and practice meaning.
