基于Petrel软件的复杂断块精细建模——以老爷庙油田东一段为例

The Fine Modeling of Complicated Fault Block Based on Petrel Software——Taking the Member 1 of Dongying Formation in Laoyemiao Oilfield as an Example

建立储层地质模型是现代油藏描述的核心和关键,它将地质上的认识用一定的数学地质方法在模型中进行预测与表征。通过构造建模,相建模和物性建模建立地质模型。构造建模是通过工区内顶底层的断层建立构造骨架模型;在精细网格骨架下以确定性的方法建立老爷庙油田的沉积相模型;通过沉积相的约束,利用序贯高斯模拟方法建立老爷庙油田的物性参数模型。建立的精细地质模型比较好的反应了地下储层的三维空间展布特征,为后期开发方案的制定提供数据体。

The reservoir geological modeling is the core and key of modern reservoir description,which applies some mathematical methods into geology and predicts and characterizes the reservoir in the modeling.Geology modeling can be constructed,through structure modeling,facie modeling and property modeling.Structure modeling is constructed by the fault in the top and bottom surface in the working area.The facie modeling is constructed by determining method in Laoyemiao oilfield.Then the property modeling is constructed by the constraint of facie modeling and sequence Gaussian simulation method,which contains porosity,permeability,oil saturation and NTG modeling.Fine geology modeling will reflect the three-dimensional conditional distribution characters in the reservoir underground better,which can provide good data system to draft the developing plan in the later stage.
