利用地震道积分技术识别三维地震解释的陷阱

Identifying 3D Seismic Interpretation Pitfalls through Seismic Trace Integrating

在铁法某井田内,利用三维地震勘探得到的地震时间剖面上并无断层显示,但巷道揭示有一个落差9m的断层,后采用三维地震道积分,在其时间剖面识别出一个与实际规模相符的断层。为此对该区所有三维地震资料进行地震道积分,解释出一条新的断层。后经巷道验证,该断层位置、性质与解释结果完全一致,可见地震道积分技术可以准确避开三维地震时间剖面上的断层陷阱。

In a minefield of Tiefa mining area, on time sections from 3D seismic prospecting have no fault reflected, but in roadways had revealed a fault with 9m throw. Afterwards, we used 3D seismic trace integrating, identified a fault on time sections accord with the actual fault size, Therefore, we carried out seismic trace integrating for all 3D seismic prospecting data, interpreted another fault, after roadway validating, its location and character are accord with interpreted result. It is obvious that the seismic trace integrating can keep away from fault interpretation pitfalls on 3D seismic time sections.
