Abstract：AVO attributes crossplot interpretation technique is to detect AVO attributes by forward simulation of models and then build up corresponding relationship among lithologic parameters of reservoir, fluid property and AVO attributes according to distribution relation of models to real seismic data on AVO attributes crossplot.Taking the analysis of forward simulation of models as a basis and AVO attributes in seismic data as an extrapolating control condition,the method closely combines the seismic, geologic and logging information together so that can reach the goal of identifying reservoir.Taking the Feixianguan oolitic beach reservoir in LJZ area of the east part of Sichuan Province as an example and through the analysis of drilling and logging data and forward simulation of models,the paper determined the response mode of seismic attributes of oolitic beach reservoir and its distribution feature on crossplot,identified the lithology of reservoir and the fluid property and further determined the gas-water interface of reservoir.
