摘　　要：本文介绍利用国际最新图形显示技术构造并显示三维地质模型的原理及模型。该模型综合地震资料及测井资料构造出各层面的形状,以水平面内的等间距网格及垂向上细分的小层将地层空间离散化成由成千上万个单元体所组成的三维地质模型体。在此基础之上,模型根据测井资料及岩心分析资料,综合多种插值方法所长,内插出孔、渗、饱等各类属性参数的分布,并将结果以三维立体图的形式输出。在人机联作的状态下,可实现诸如旋转、放大缩小、调配颜色等多种图形功能。This paper presents the principle and model for constructing and displaying 3-dimension- al steadystate geological model by means of the latest graphic technique in the world. The model constructs the shape of each layer by integrating seismic and well logging data, and the formation space is discritized to a 3-dimensional geological sturcture composed of thousands of cells. The largers are divided in vertical direction and equal interval grids are used. Further more, the model interpolation the data of porosity,permeability,saturation and other parameters from well logging and core analysis data by using many interpolation methods available, the results are output as 3-dimensional stereoscopic diagrams.
