| 中文摘要:在三维地质模型中，不能有效的分析地层与断层之间的形态与结构，提出了基于TIN-Octree混合空间数据模型的精细三维地质体构建方法。分析两者的地质形态与连接状态，形成良好的数据映射剖面，并利用Octree的编码特性，增加对象的描述精度以及存储性能，可以有效地为油气勘探开发提供可视化效果。并结合实际地质地震勘探解释成果资料的应用，表明该模型构建方法可以有效地建立地质体三维模型，具有良好的应用价值。 |

| Abstract:In 3D geological models，the form and structure between strata and faults can not be effectively analyzed. A method of constructing fine 3D geological body based on TIN-Octree mixed spatial data model is proposed.The geological morphology and connection state of the two are analyzed.A good data mapping section is formed.And using the encoding characteristics of Octree，Increases the description accuracy and storage performance of objects.It can effectively provide visual effects for oil and gas exploration and development.Combined with the application of the actual geological seismic interpretation results，It is shown that the method can effectively establish 3D models of geological bodies.It has good application value. |
