摘　　要：针对油田地质工程的特点,将地层抽象为规则方格组成的集合,基于离散的地质钻孔信息,以规则网格法实现地层的几何建模;采用Kring插值法将离散钻孔内地层属性值插值得到各地层层面网格点处的地层属性值,提出根据网格点处属性值对空间任意点处的属性进行插值的形函数方法。开发油田地质建模软件GeoPetrel以实现三维地层的可视化、地质柱状图及地质剖面图的绘制等功能。For the oilfield geologic information project, the geometry modeling is realized by regulation grid method which transforms the discrete drill data to regulation grid collection. A method called Kring interpolation is used to acquire attribute values of layer-upon-layer grid points from the interpolation of the drill data get-property, And the shape function is brought forward to get any space point＇s property from the attribute values. Based on the method, the 3D visualization of geological entity, the drawing of geologic column and the drawing of geologic section can be realized by the software called GeoPetrel for oilfield geologic modeling.
