摘要
在定向井钻进中 ,钻头的定位 (即井眼轨迹的实时测量 )是至关重要的。尤其对于导向钻井、井下闭环自动钻井以及将来的人工智能钻井更是必不可少的重要一环。文中介绍了新一代地下定位系统的设想、内容以及实现的可能性。并结合石油钻井工程的实际情况 ,提出了三种可能实现的新型地下定位系统———地下GPS(全球定位 )系统、地下雷达和地下CT(计算机断层扫描 )。讨论了新型系统的原理与构成 ,以及需要解决的发射波段问题。并展望了 2
It is of importance to position finding of bit for orientational drilling.Specially it is essential to downhole closed loop automated drilling and intelligent drilling in the future.This paper introduces a new underground positioning system and it's idea,content and reality.According to the realities of drilling engineering,it provides three new nuderground positioning systems underground GPS,underground radar and underground CT.The principle and technical structure for the new type systems and penetration frequency has been discussed.Also we look forward a prospects to the applied perspective of new underground positioning system in drilling engineering and other engineering for the twenty first century.
