Abstract：The interpretation of three-dimensional seismic data structure area was finished in the following steps: 1. Seismic horizons are correlated with geological analysing drilling data and various logging curves. 2. Seismic horizon picking and time structure map in Nanyishan horizons by were achieversby using Apollo workstation's SEISTAR interpretation software package which can correlate vertical section with time slice. 3. Three-dimensional velocity data volume was made by performing various corrections of available sonic logging curves in the area. 4. Average velocity map for seismic horizon interpretation was plotted by using the three-dimensional velocity data volume and time structure map. 5. Depth structure map was drawn by making necessary mathematical operation of data files about time structure map and average velocity map with the use of corresponding module of Apollo workstation's MSAPSTAR software package. The comprehensive analysis of drilling and seismic informations shows that the rich hydrocarbon seismic horizons in the Nanyishan structure are mainly characterized by low frequency, low velocity and high energy. So, the distributions of rich hydrocarbon reservoirs in top Oligocene (E3)and mid pliocene (N2)series were ascertained by using the seismic characteristics.
