【Abstract】 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.更多还原
