基于GoCAD和钻孔数据的地下油库三维地层建模

Three-dimensional stratigraphic modeling of underground oil depot based on GoCAD and drilling data

鉴于二维的地质模型已经很难满足工程的需要,基于GoCAD软件依据某水封油库的钻孔资料借助距离幂次反比插值模拟地层界面、生成地层界面模型并建立洞库模型,分析展示了各个地层的相对关系以及与洞库的交切关系,利用GoCAD强大的可视化功能在地层分析、工程选址及勘测数据的反向验证等方面为地质勘察及工程建设提供了参考和依据。

In view of the fact that the two-dimensional geological model can hardly meet the needs of engineering, this paper simulates the formation interface, generates the formation interface model and establishes the cavern model based on the GoCAD software and the inverse interpolation of the distance power based on the borehole data of a water-sealed oil depot. The analysis shows the relative relationship of each stratum and the interaction with cavern. The powerful visualization function of GoCAD provides reference and basis for geological exploration and engineering construction in stratum analysis, engineering site selection and inversion verification of survey data.
