对特定区域进行体模拟

李二饼

请教个问题：petrel09中，我现在file:///C:\Documents and Settings\Administrator\My Documents\Tencent Files\869536107\Image\Image4\RXZ9_4(MR7)YR}7AYAP(4XX.jpg粉色的是井工区边界，但是在做模型的时候make simple grid，我只想对红色的区域进行facies modeling，请问怎么能实现呀，file:///C:\Documents and Settings\Administrator\My Documents\Tencent Files\869536107\Image\Image4\Q3DL0L%](XXJ}1`4XHSG9AV.jpg在这里如果只添加红色区域的边界，只能对某一个层进行modeling，可是我现在有很多层，能不能在哪里设置一下，只对红色区域进行facies modeling，毕竟不是每一个层的红色区域是大小、形态一致的，望赐教，谢谢！

Hierarchical Facies Modeling

Facies models can be constrained by a second level of facies model in much the same way as in Petrophysical modeling. A large scale facies model can define regional channel belts or a transition from shoreface to deep marine facies. Conversely, a smaller scale facies model would model local variations within these regions.

Modeling facies at two different scales requires separate discrete well logs describing the facies at each of these scales. One log will represent the large scale facies regions, and the second will represent the individual facies seen in the well.

How to get a Hierarchical Facies model:

• Generate a new discrete facies log to differentiate between the different lithologies (for example, fine grained sand and silt representing the levee facies in an already existing facies object model).
• Upscale the new discrete facies log.
• Open the Facies modeling process and make sure the new facies log is selected.
• Select Sequential indicator simulation as the modeling method.
• Click on the Facies button to select the already existing facies object model that defines your regional facies (levee, for example).
• In the Facies tab, drop in the new facies (fine grained sand and silt) to distribute in the regional facies (levee).
• For each new facies, define the Variogram parameters and the Fraction.
• For other regional facies (as channel or shale, for example) select the modeling method Assign values. Under the Settings tab, select Constant and the correct facies code for every one.
• Click Apply or OK to run the process.

恩，郝哥，我先看看，有点费劲，我得翻译翻译。回复的较慢，对不住了，谢谢郝哥的关注！
