摘　　要：结合地震解释剖面图与地质构造平面图上的断层信息,采用数字化技术提取断层建模所需的相关数据,以剖面为建模基础,采用空间线性插值技术构建了三维断层模型。该方法能充分利用平面图和剖面图特征,从整体上把握断层,提高断层建模的准确性。通过开发相应软件实现了地质体模型断层的添加和修改。The data needed for fault modeling are extracted from the fault information in seismic interpretation section map and geological structure plane using digital technology,the profile is as the basis of fault modeling,and 3D fault model is constructed by using spatial linear interpolation technique. The modeling method can make full use of the features of the plane and section maps and improve the accuracy of fault modeling by grasping the faults in the whole. The adding and modifying of the faults in the geological body model is well implemented by developing the corresponding software.
