In view of special geologic conditions such as the characteristic complex structures (small structure,small faulted block,small faulted nose and multi faults) and complex reservoirs that have the thin,narrow and variant feature,we carried out the study of high precision 3 D seismic interpretation.Using 3 D visualization,coherent data volume,horizontal slice and map analysis to finely interpret the 3 D structures,the ability using seismic exploration for identifying underground complex geologic structure and anomalous seismic reflecting body has been greatly improved.We used fine geologic prediction,attributes analysis and multi well constrained inversion technique for integrative lithologic interpretation of reservoirs having thin and interbedded characteristics,quantitatively predicted and described the rule of spatial distribution and variation for single sand bed.The set of techniques fully displayed the priority of 3 D exploration and achieved good seismic and geologic effects in oilfield exploration and development.
