Establishment and application of the parameter interpretation models of Y9 reservoir in V block of Longdong Oilfield

V block in Longdong Oilfield is in the middle-high water-cut stage.For the purpose of fine geology study and improving the development effect,3D geology model must be built,and then the second interpretation of logging data is finished.Therefore,on the basis of a great deal of literature research,the four-property relationships of Y9 reservoir are studied by the core data and geology data,logging data and production performance data and according to the rule of geology data restricting logging data and core data calibrating logging data.Moreover,the interpretation models of shale content and porosity,permeability and oil saturation are established,the models are loaded on the log interpretation platform,and then the second interpretation of the logging data is fulfilled.The research indicates that the correlation analysis between the core data whose depth is determined and standardization logging data is reliable.The application of the established reservoir parameter interpretation models is successful.
