| 摘 要： | 在三维地层建模过程中,一些复杂的地质构造(如倒转褶皱)往往需要人工干预才能生成正确的模型。针对地质体的特点,提出一种三棱柱模型的改进算法,将核心序列优先等方法运用于建模过程,同时运用虚拟钻孔柱的方法处理尖灭,在无需人工干预的情况下较好地实现了对复杂地层倒转现象的模拟。

| Abstract: | During setting up the 3D-stratum model,some complex geological structures such as overturned fold always have to be set up manually.According to stratum characteristics,an improved algorithm based on tri-prism model is put forward,in which methods such as Core-Sequence First are used in process of modeling and the pinch out of stratum is achieved with the insertion of Virtual-Borehole.Based on these,simulation of complex overturned stratum is well realized without manual operation. |
