三维和四维工区的规模、工区个数及与之相关的地震数据都在以指数的方式不断攀升;而与此同时,工业界却在要求更精细的地质解释和更短的工作周期。VoxelGeo(基于三维数据体的可视化及解释系统)为这一需求提供了一个综合解决方案。利用VoxelGeo对公山庙区块的构造、地层和振幅特征进行了综合研究,通过三维体快速扫描,快速认识构造模式和沉积体系,进而识别出地质异常体。在此基础上,综合沉积、构造、烃源及储集等诸多地质因素,分析了区内已知砂岩油藏的成藏条件及油藏的受控主因素。
The size of the three-dimensional and four-dimensional workplanes, the number of workplaces and the associated seismic data are all exponentially rising; at the same time, the industry is demanding finer geologic interpretations and shorter work cycles. VoxelGeo, a three-dimensional data-based visualization and interpretation system, provides a comprehensive solution to this need. Using the VoxelGeo, the authors made a comprehensive study of the tectonic, stratigraphic and amplitude characteristics of the Gongsamiao block, and quickly realized the tectonic models and sedimentary systems through rapid 3D body scanning to identify the geological anomalies. On this basis, the accumulation conditions of reservoir and the controlled main factors of the reservoir are analyzed based on the geological factors such as sedimentation, structure, hydrocarbon source and reservoir.
