Abstract: Well log and seismic data have their advantages and disadvantages in the study and interpretation of structural patterns.To integrate seismic with well log data in a complementary way for the analysis of structural patterns is the trend in the future.Because of the complexity of underground structures,the interactive interpretation system is adopted,it gives flexible interpretation models and methods.The results which were processed by the dipmeter interactive interpretation expert system(DIPES) were accordant with interpreted results from 3-D seismic data.Structural patterns of fault block Wen-88 in southern Wendong of Zhongyuan oilfield were analyzed by using DIPES.The data of following wells,Xinwen-88,Pushen-4 and Pushen-12,were processed,together with the information of seismic,geology and other well log,2-D and 3-D structural pattern diagrams were obtained.The interpreted conclusions have been accepted by geologists and are confirmed by drilling and geologic data.DIPES can be run in various kinds of workstations that are based on UNIX operating system.
