Abstract:The interpretation of 3-D seismic data in Wennan prospect (about 200 km2),Dongpu depression, brings the following geologic results. 1.The unreasonable 2-D interpretations of strike faults and cross faults nave been corrected to improve the accuracy of fault interpretation. The conformability between interpreted faults and drilled faults increased by a factor of 22.3%. 2.The shapes of interpreted structures in this prospect were further ascertained to improve the conformability between drilling and interpre/tation. Three ones of faulted rose and small buried hill were newly discovered. 3. The mistakes in stratigraphic horizons in the well Wen 113 have been corrected. Oil-bearing sand area in low section of S2 formation increased by 26.9 km2.These achievements show that 3-D seismic exploration is indeed superior to 2-D seismic exploration in prospecting for details of geologic structure. Thus, 3/D seismic exploration is very suitable to the area where 2-D seismic data are poor, but oil reserves maybe discovered.
