构造框架模型是三维地质模型的基础,影响了相建模、属性建模和储量计算。通过多年的建模经验总结,认为构造建模质量控制的关键点包括断层模型和层面模型。断层模型质量控制的关键点包括:断层面应与井点断点数据匹配;合理表征断层面空间形态;合理表征各级断层之间的组合关系。层面模型质量控制的关键点包括:层面与井点地质分层数据一致;准确反映构造形态和特征;正确反映地层间的空间接触关系。上述构造建模质量控制方法已在大量油气田的储层建模中得到应用,并取得了较好的效果。
Tectonic framework model is the foundation of 3D geological model, affecting phase modeling, attribute modeling and reserves calculation. After years of experience in modeling, it is concluded that the key points in the quality control of construction modeling include fault model and level model. The key points of fault model quality control are as follows: the fault plane should match with the well point breakpoint data; the reasonable characterization of the fault space shape; and the reasonable characterization of the combination relationship between fault layers. The key points of the quality control of the level model include: consistent with the geological stratification data of well points; accurately reflecting the tectonic forms and features; and correctly reflecting the spatial contact relationships between strata. The above-mentioned method for quality control of structural modeling has been applied to reservoir modeling in a large number of oil and gas fields and has achieved good results.
