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。
The tectonic model is the foundation of 3D geologic modeling. The tectonic model established by comprehensive drilling, seismic interpretation and stratigraphic correlation results reflects the developmental features of faults and strata in the three-dimensional space. The quality of the structural model determines the successor properties of the model, the results of reserves calculations, and the quality of the dynamic model. Through the review of basic data, the fault model, plane grid, layer model and vertical grid quality are controlled, the quality control of the whole process of structural modeling is realized, and the quality of structural model is improved. After the validation of the sea cucumber 5 buried hill structural model, the fault model of the structural model established by this method accurately reflects the spatial position of fault, the fault element and the correlation between the faults. The layered model integrates the advantages of seismic data and well contrast data , Which truly reflects the stratigraphic development characteristics. The grid direction and step parameters are reasonable and effective, which can not only accurately reflect the current geological understanding but also improve the computational efficiency of the model.
