摘　　要：建立数字化地质模型,能够提供多角度、多细节的观察手段,提高油气资源评估的准确性,方便不同领域的专家的交流和协作.采用逐点添加、局部优化的Watson算法,能够生成包含边界、断层、离散数据点的约束Delaunay三角网格,用约束Delaunay三角网格生成地质区块的多个地质层面模型,并组合成闭合的三维地质构造模型,为地质勘探数据的分析和数据场的可视化提供了重要的基础.The digital geological model can provide the multi-views and multi-resolution of the underground structure, and improves the accuracy of evaluating oil and gas resources, and thus it is convenient to communicating and coopera- ting of different fields experts. Using Watson method of adding point by point and local optimization can create constrain- ed Delannay triangular mesh containing boundary, fault and scattered data. Constrained Delannay triangular mesh creates a series of geological surface models. These models are combined to form closed three-dimensional geological model that provides important basis for the analysis of geological exploration data and the visualization of data field.
