Petrel断层模型质量控制
Quality control of the fault model The end result must be a fault model which accurately represents the input data provided along with your own interpretation of the structure. As well as this, the generated fault model must comply with a few rules in order for the 3D grid to be created by the gridding algorithm without too many problems. 断层模型质量控制 最终结果必须是一个精确再现你自己对构造解释的一个断层。不仅如此，生成的断层模型还要符合如下简单规则不至于网格化时出现太多问题： isc]- Always connect crossing faults 总是连接交叉断层。
- Truncated faults must be properly truncated to each other, Key Pillar by Key Pillar. End truncations must be connected. 削截断层必须是逐个主定型断杆相削截。削截的末端必须相连。
- In general, keep the top and base Shape Points of the faults as even as possible. 总体而言，保持断层上的顶底定形点尽可能均匀分布。
- Keep the pillar geometry as simple as possible. There is no point in creating a listric fault if it is not needed. 保持断层杆的形状尽可能简单。如无必要，尽量避免建立犁式断层。
- Keep the shape of the faults as simple as possible. Minimize the number of Key Pillars in each fault - they shall only define the shape of the fault, not sample the data at close intervals. 尽量建立形状简单的断层。每一条断层上保持最少量的主定型断杆，这些定型断杆仅代表了断层的形状，没有必要以网格步长来的密度来排列主定型断杆。
总体原则：
连接交叉断层、
削截断层至少有一对主定型断杆、
顶底定形点均匀分布、
断层杆形状简单、
避免建立犁式断层、
断层形状简单、
主定型断杆少而精。
