摘　　要：连井剖面是用于地层对比及储层精细研究的一种重要分析手段。针对传统连井剖面二维显示不够立体直观及三维垂直投影显示又无法展示空间曲面信息的问题,通过研究三维空间中连井剖面绘制技术,提出了一种实现方案。根据地震数据体信息,基于井身轨迹的空间几何特征,运用计算几何学、空间立体几何原理,得到井身轨迹的井身参数方程,构建三角网格,采用三角网拓扑技术、纹理映射技术和光照模型技术实现了沿井轨迹的连井剖面三维可视化。通过实际研发应用取得了良好效果,为研究储层的空间展布特征及各种储层物性参数的空间变化提供了一种新颖的三维可视化分析手段。The connecting-well Section is a critical stratigraphic correlation and fine reservoir research analysis method.Aiming at the problems that the connecting-well section in a two-dimensional display is not stereoscopic and intuitive and that using the vertical projection in three-dimensional space cannot show the spatial curved surface information,an implementation scheme is proposed through the study of the drawing technologies of the connecting-well section in three-dimensional space.According to the seismic data,based on the spatial geometric characteristics of the well traces,the well traces'parameter equation is obtained using the theories of computational geometry and solid geometry,and then the triangular mesh is constructed.The 3D visualization of the connecting well section along the well traces is realized using triangular mesh topology,texture mapping,and lighting model technologies.Good results have been achieved through research and application,which provides a novel 3D visual analysis method for researching the spatial distribution characteristics of reservoirs and the spatial changes of various reservoir physical parameters.
