Application and research of high-precision 3D seismic comprehensive interpretation technology

摘要

In view of the geologic character of minor faults, small-scale structures and thin interbeds in south songliao basin, a research work in high-precision 3-D seismic exploration interpretation method has been made, a new and characteristic interpretation technology comes into being. Seismic interpretation adopts 3-D visualization, coherent volume, horizontal slicing and map analysis techniques achieving full 3-D fine structural interpretation, and adopts fine geological prediction, seismic attributes analysis, multi-well constrained inversion techniques achieving comprehensive description of lithology in the thin interbed. These improve the ability of seismic exploration to identify complicated structures and anomaly reflected bodies, predict and describe quantitatively the rule of space distribution of sand bodies. It is very useful for searching suppressed hydrocarbon reservoirs.
