Abstract:Faced with the characters of "less wells,larger well interval and taking the seismic data as major source"in Zhangdong area of Dagang beach,the paper presented the idea,content,method and technique of fine seismic-geologic prediction.Integrative application of geology,sedimentology and multiple technical tools such as seismic and logging is key to carry out accurate prediction and fine description of lithologic oil/gas reservoir.Based on the characters of large lateral variation and strong physical non-homogeneity of targets in the studied area,the paper adopted pseudo-acoustic random impedance inversion and combined with seismic frequency spectrum analysis to carry out fine prediction of lithologic reservoir.The results showed that the sand-body predicted results was coincident with interpreted results of logging data,which can be taken as basis of studying oil/gas distribution regularity and integrative appreciation.
