Petrel构造模型质量控制方法研究

摘要
构造模型是三维地质建模的基础,综合钻井、地震解释和地层对比成果资料建立的构造模型反映了三维空间内断层和地层的发育特征。构造模型的质量决定了后续属性模型、储量计算结果乃至动态模型的质量。通过基础数据复查,对断层模型、平面网格、层面模型、垂向网格质量进行控制,实现了构造建模全过程质量控制,提高了构造模型质量。经过海参5潜山构造模型的验证,利用该方法建立的构造模型中断层模型准确反映了断层的空间位置、断层要素及断层之间的相互关系;层面模型综合了地震资料和井对比资料的优点,真实反映了地层发育特征;网格方向、步长参数合理有效,既能够准确反映当前地质认识又提高了模型运算效率。
Structure model is the foundation of geological model. Well data, seismic interpretation data and stratigraphic correlation result are used to build a structure model, which reflects the feature of faults and stratigraphic characteristics. The quality of structure model has a great impact on property model, reserve calculation and dynamic model. Reviewing the basic data and controlling the quality of fault model, horizon model and 3D grid can improve the quality of structure model. This method has been proved to be practical and effective by the structure model of Haican5 buried hill reservoir. Fault model in structure model can reflect the characteristics of the faults. The horizon model which combines seismic interpretation data and stratigraphic correlation result, can reflect the features of formations. The grid direction and grid spacing are reasonable. It not only accurately reflects the current geological knowledge,but also improves the efficiency of modeling.
