Abstract

Elastic modulus can be used to characterize various lithology and fluid in reservoir.However,the results are always ambiguous

by single elastic modulus.Since elastic modulus fluid factor (EMFF) owns the properties of both bulk modulus and shear

modulus,based on the crossplot of bulk modulus against shear modulus,EMFF was introduced to reduce the ambiguity of

reservoir prediction.In application,EMFF could be constructed from elastic modulus parameters which could be obtained from

pre-stack elastic parameters inversion and petrophysical results.On the basis,fluid identification and reservoir prediction can be

realized.The application result at Yongxin Block of Shengli Oilfield shows that the constructed EMFF could identify the oil

reservoir efficiently.
