【摘要】 随着勘探开发水平的提高、勘探开发难度的加大,油气勘探对工程技术的要求越来越高。将三维可视化技术应用于钻井轨道设计和检测的三维可视化井筒动态监控技术能够直观形象准确的展示三维井身结构和井身轨迹、实时模拟钻井过程,为优化钻井、加快勘探周期,提高勘探开发的效益提供技术支持。本文介绍了国内外三维井眼轨迹显示、井筒检测技术研究的发展轨迹,对比了几个典型性的应用系统的特点。指出,目前在国内还缺少将钻井现场各专业数据集成在井筒轨迹上的三维可视化相关系统,也缺乏相关的监控信息的交互操作。本文结合三维可视化井筒动态监控系统的开发实践,给出了系统的整体设计,重点介绍了在钻井眼轨迹的三维可视化、老井轨迹的三维可视化、在钻井与老井的防碰扫描、在钻井与设计井轨迹的偏离扫描等四个模块的功能设计、模块对象的序列交互以及模块实现。在模块实现部分介绍了在钻井查询及三维轨迹绘制、老井查询及三维轨迹绘制、在钻井与老井的防碰扫描的算法分析及设计。本系统在VC++6.0环境下结合OpenGL三维图形库实现,能够实现在钻井眼轨迹的实时显示,老井轨迹的三维显示,实钻井眼轨迹与设计井眼轨迹的偏离检测以及实钻井眼轨迹与区域内老井井眼轨迹的碰撞检测等功能,为三维井眼轨迹的动态监控的实现提供了一种参考。更多还原

【Abstract】 With the improvement of exploration and development level, the more difficult exploration and development, more and more high to the requirement of engineering technology of oil and gas exploration. 3-D Visualization Technology is applied to the drilling track design and testing of 3-D Visualization Shaft Turn Visual Image Dynamic Monitoring Technology.This technology can accurately show the three-dimensional well bore structure and well bore trajectory, the real-time simulation of drilling process. In order to optimize the drilling, to speed up the exploration cycle and to improve the benefit of exploration, this technology can provide technical support. This article introduces domestic and overseas three dimensional borehole trajectory display, wellbore detection technology research and its development process. The characteristics of several typical application systems are compared in this article. It reports that the drilling site major data integrated on the wellbore trajectory of the 3-D Visualization Relevant Systems and mutual operations based on different related monitoring information are also lacking in domestic at present.Dynamic monitoring system is based on 3-D visualization wellbore development practices. Then the overall design of the system is presented. This article introduces four modules in wellbore trajectory of 3-D visualization, 3-D visualization of old well trajectory, in crash-proof scanning between the drilling well and the old well, in deviation scanning between drilling well and the Designed-well-trajectory. Functional design, module object interaction and module implements are based on these four modules. The part of module implements introduces the analysis and design of the algorithms based on drilling query and 3-D trajectory drawing, old well query and 3-D trajectory drawing, crash-proof scanning between the drilling well and the old well.This software system are implemented on the VC++6.0n platform with the OpenGL 3-D graphics library. This system can apply in the real-time display of wellbore trajectory, 3-D display of old well trajectory, deviation detection between drilling well and the Designed-well-trajectory, crash-proof detection between the drilling well and the old well. This system can provide a reference of dynamic monitoring for 3-D wellbore trajectory.更多还原
