三维可视化技术与油气藏综合评价

三维可视化技术是一项地震资料解释新技术 ,与传统的二维解释技术不同 ,它基本抛开了原来由点到线再到面的工作思路 ,充分利用三维地震资料的空间连续性和零闭合差等特性 ,通过全三维解释形成地质认识 ,并通过层面可视化评价三维空间中的层面。该项技术结合相干体技术可进行复杂断层的解释与组合 ;采用种子点自动追踪模式解释波阻抗界面 ,落实构造形态 ;直接在三维空间上寻找和雕刻特殊地质体 ,研究储盖组合等。三维可视化技术的应用大大提高了地震资料解释工作的效率和成果精度 ,所获成果更为直观、可靠 ,在 HY7- 1构造等实际“靶区”取得了诸多地质上的新认识

3D VISUALIZATION AND INTEGRATED RESERVOIR EVALUATION

3D visualization is a new technique of seismic interpretation and is completely different from the traditional line based work model. It takes full advantage of the spatial continuity and zero close difference of 3D seismic volume, and enable us to acquire geologic cognizances by full 3D interpretation and to evaluate horizons in 3D volume by horizon visualization. It is widely applied in such fields as fault interpretation on 3D coherence volume, structure deliniation through auto tracing impendance interfaces by seedpoint, and direct seeking for and de scribing special geologic bodies and reservoir seal associations. 3D visualization technique has greatly improved the accuracy and efficiency of seismic interpretation, and made the final results more reliable and intuitive. In practical "targets" such as HY7 1 structure, application of 3D visualization technique has resulted in a number of new cognizances in geology.
