模型地质信息提取及在不同网格系统间的转换
|
摘要
针对地质模型粗化到油藏模型中存在地质信息丢失的问题,通过在地质模型中对复杂或小尺度地质信息进行简化和等效,然后提取包络面,再通过网格锯齿化算法实现地质信息在油藏模型中的转化。以渤海Q油田为例,阐述了该方法的具体应用,同时验证了该方法的可行性。
In order to solve the problem that the geological information is lost when geological model is converted to reservoir numerical simulation model by coarsening,the complicated or small-scale geological information in the geological model was simplified,then the envelopesurface was extracted,and finally the geological information was converted to the reservoir numerical simulation model by grid sawtooth algorithm. Taking Q oilfield in Bohai as an example,the specific use process of the method was described,which also verifies the practicability of the method.
