摘　　要：石油勘探开发是石油工业的重要部分,在石油勘探开发过程中,会采集到大量的数据,形成三维数据场,使用这些数据的目的是为了准确地再现油藏分布以及石油勘探开发过程中的参数的动态变化。该文是将三维数据场可视化技术应用到石油勘探开发过程中的地质建模和数值模拟之中,利用可视化技术,尤其是三维数据场可视化技术,实现了从大量数据中构造出三维图像。该文在算法中使用了包围盒技术和分层存储结构来提高算法的速度,达到了较好的效果,直观地再现了石油在油气藏中的状态,指导设计人员进行井位的确定,提高石油生产的效益,辅助相关领域工作人员的分析、设计,具有广泛应用前景。Petroleum exploration and exploitation are important parts of the petroleum industry. In the process of oil exploration and exploitation, a great deal of data can be collected. These data form 3D data sets. The aim of using these data is that it reappears oil distributions and parameter dynamic change intuitively and truly in course of petroleum exploration and exploitation. The article applies 3D data sets visualization technique to the geological modeling and numerical value simulation in course of petroleum exploration and exploitation and by using visualization technology realizes the construction of 3D image from 3D data sets visualization technology. The article uses envelopment box technique and bedding storage structure in algorithm for enhancing speed of algorithm, and to achieve a better effect. It reappears oil distributions and parameter dynamic change truly in course of petroleum exploration and exploitation, and directs the designers to make sure of the wells＇ locations and to improve the effectveness of oil production.
