三维可视化解释技术在DF气田的应用
|
摘要
三维可视化解释技术在DF气田气藏描述中的应用效果表明 ,以方差体与相干体技术为基础 ,利用层位自动追踪技术和层面可视化及沿层精细雕刻等三维可视化解释新方法 ,不仅能够从三维空间整体把握该气田气藏的构造和沉积特征 ,避免地震解释的随意性 ,而且可以提高地震解释的精度和效率 ,使地震信息的利用率大大提高。
A 3D visualization technique of seismic interpretation has been applied to reservoir description of DF gasfield. This technique is based on coherence cube and variance cube, and makes use of some new interpretation tools such as layer auto-tracking, bedding surface visualization and detailed bedding sculpting. The results show that this technique can hold overall 3D structure and sedimentology of the reservoir, avoid arbitrariness in seismic interpretation, improve interpretation accuracy and efficiency, and increase greatly utilization of seismic information.
