井筒信息动态处理及展示系统研究

随着油田信息化的深入,油田信息化面临着信息可视化分析、不同行业人员协同工作、信息资源共享等困难和挑战。本文应用虚拟现实技术从基于VR的三维模型构建入手,通过介绍建模的流程以及建模的关键技术——实例技术、LOD技术、纹理映射技术,并构建了各类井筒工具。构建地层模型,通过粒子系统模拟井下措施。利用该系统用户能够完成井筒的自动装配、进行油水井的工程设计以及油水井措施的三维动态展示等功能。该系统能够为用户提供完备的数据库信息查询,能够直观地显示出井筒的各部分组件信息、完井状况和生产措施等情况,有利于工程设计人员展示、汇报和分析总结。

Research of a Wellbore Information Dynamic Processing and Display System

With the in-depth of oilfield information, it faces the difficulties and challenges of information visualization analysis, different industry personnel collaborative work and information resources sharing. This paper is based on the application of virtual reality technology from the 3d modeling of the VR, introduces the process and modeling and key technique-examples technique, LOD, texture mapping and constructing avarious wellbore tools. It constructs a stratigraphic model and uses the particle system techniques to simulate the underground measures. Using this system can accomplish the automatic assembly, wellbore oil-water Wells engineering design, and oil wells measures such as the dynamic 3d display function. The system can provide users with complete information from a database query, can intuitivey show each part of the component information wellbore, completion status and production measures for engineering design personnel, display, reporting, analysis and summarization.
