我们对北海3D地震数据集进行射线追踪的研究已经完成。研究表明在地震、测井和地质信息集成的基础上对深度图进行解释相对容易些,应用一稳定的3D三角形化射线追踪法计算了目的层的深度图。 初始输入模型与3D数据体中地震双程时间剖面上拾取的层位的几何形态相对应。一个专用工作站环境被用来模拟和显示现有测试数据。目前的研究集中于深度模型的改进上,而这一模型的改进是通过射线追踪方法来实现的,该方法吸收了界面表面三角形化和在四面体体积中进行计算的优点。
Our research on ray tracing of the North Sea 3D seismic data set has been completed. The study shows that it is relatively easy to interpret the depth map based on the integration of seismic, logging and geological information. The depth map of the target layer is calculated using a stable 3D triangulation ray tracing method. The initial input model corresponds to the geometry of the horizon picked up on the seismic two-way time profile in the 3D volume. A dedicated workstation environment is used to simulate and display existing test data. The current research focuses on the improvement of the depth model, which is improved by the ray tracing method. The method absorbs the advantages of triangulation of the interface surface and calculation in the tetrahedron volume.
