摘要
In submarine Block A,traditional post-stack wave impedance cannot effectively predict the fluid-distribution range because of low ability of P-impedance to identify gas and water.In this paper,we adopt the pre-stack extended elastic impedance(EEI) inversion technique.EEI inversion technique including more information about lithology and fluids is an effective technique for the fluid detection and recognition.On the basis of briefly presenting the concept,method and principle of EEI,we use this inversion method to the submarine Block A.We check the sensitive parameters for fluid detection,optimize the optimal theory angles for fluid detection,and calculate the EEI curves for fluid detection.The results show that the pre-stack extended elastic impedance inversion is favorable for the submarine reservoir fluid identification,especially for the gas and water detection.So the effective fluid identification is established for deep submarine fans.
