基于地层切片的地震沉积解释方法

Seismic sediment interpretation method based on strata slice

基于地层切片的地震沉积解释方法是随着三维可视化技术的发展而兴起的一种三维地震解释新方法。通过建立等时格架约束下的高密度地层切片,结合剖面精细构造解释,能够从平面和剖面两个视角互动解释地震资料。在高密度地层切片上进行沉积微相的解释,大大提高了地震资料的利用率,真正做到了全三维地震解释,同时平面和剖面的互动解释,解决了因为地震纵向分辨率低,在剖面上很难识别沉积微相的问题,降低了解释难度,大大提高了解释效率。

The seismic sediment interpretation method based on strata slice is a new method, which sprang up along with the 3D visualization development. The seismic data can be interpreted from two visual angles （plane and lateral section） through building high density strata slice constrained by equitime-framework and combining fine structure interpretation. The utilization ratio of the seismic data can be upgraded by interpreting the microfacies on the strata slice. It is full 3D seismic interpretation.The interpretation through two visual angles （plane and lateral section） resolves the problem that it is difficult to identify the microfacies because of the low seismic resolution. It makes the interpretation easy and raises the interpretation effectiveness.
