【Abstract】 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.更多还原
