【摘要】 在油田开发过程中,为准确检测地下输油、输气、输水管线及光缆、电缆的分布和走向,提出基于OpenGL的地下管线三维成像系统:首先,利用磁异常信号探测系统对地下管线磁异常信号进行采集;其次,将采集到的磁异常信号进行处理并提取有效数据;最后,利用Visual C++和OpenGL平台对油田地下管线探测数据进行可视化成像,并通过探测系统屏幕直观反映管线的位置及分布.现场结果表明,基于OpenGL的地下管线探测数据三维成像方法对于油田地下管线可视化探测行之有效.更多还原

【Abstract】 During the process of oil field development, in order to accurately detect the position and trend of oil, gas, and water pipeline or other buried pipelines and cables in oilfields, the 3D imaging system used in detecting these buried pipelines is proposed based on OpenGL in this paper. Firstly, the magnetic anomaly signals produced by the presence of buried pipelines are collected by using the buried pipeline detecting system. Secondly, the collected signals are processed, and then the effective magnetic anomaly signal is extracted. Finally, by using Visual C++ and OpenGL, the 3D imaging and visualization is realized for the detecting data, and the position and trend of buried pipelines can be visually observed on the screen of buried pipeline detecting system. The results show that the 3D imaging method for the detecting data based on OpenGL is effective in visualized detection for the oilfield buried pipelines.更多还原
