三维地震沉积解释方法初探

The introduction of 3D seismic sediment interpretation method

三维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 method of 3D seismic sediment interpretation is a new method,we can interpret the seismic data through plane and lateral section two visual angle by building high density strata slice restricted by equitime-framework and fine structure interpretation,we can upgrade utilization ratio of the seismic data by interpret the microfacies on the strata slice.We can reach full 3D seismic interpretation.The interpretation through plane and lateral section two visual angle resolves the problem that it is difficult to identify the microfacies because of the low seismic resolution,makes the interpretation easy and develops the interpretation ratio.
