Abstract: The three-dimensional visualization system was applied to the underground environment modeling and software architecture design in drilling engineering.The real-time interpretation,analysis and display of measurement data of drilling parameters could be realized by three-dimensional geological modeling.The polygon modeling structure method,parameterization curved surface structure method and subdivision curved surface structure method were analyzed.On the basis of the improved subdivision curved surface structure method,the complex objects in the real world were constructed and demonstrated using OpenGL.Some underground geological models in drilling engineering could be formed.The three-dimensional model of wellbore trajectory,well target, electrical log curve and drilling log curve could be constructed.The three-dimensional visualization system can offer the advanced visualization assistance for the production of oil filed.

Key words: drilling engineering, three-dimensional visualization technology, geological model, database, three-dimensional model

摘要： 应用三维可视化技术对地下地质环境和钻井状态进行了三维描述,对常见的多边形建模构造、参数化曲面构造及细分曲面构造等方法进行了分析。以改进的细分曲面构造方法为基础,利用OpenGL开发语言建立了真实世界中复杂物体的构造和显示方法,形成了描述钻井工程中断层、地层(油、气、水层)、地震体、地震层速度垂直剖面等各类地下模型,同时构建了井轨迹(设计轨道、实钻轨迹、预测轨道)、井靶点、测井及录井曲线的三维显示模型,实现了实时显示、分析和解释MWD数据和钻井作业数据的操作。
