摘要
SmartMag定向钻进高精度中靶系统是在地面经过数千次的试验后,于2009年首次进行工业性实验。结果表明,在已应用的23对对接井中,SmartMag系统性能良好、精确度高,对引导对接起到了至关重要的作用。介绍了该系统的结构原理和技术指标,总结了应用经验和技巧。
Developed independently by Institute of Exploration Techniques,SmartMag high precision drilling guidance system can substitute the similar imported instrument.After being tested thousands of times on the ground surface,SmartMag was brought to the construction site in Turkey for its first industrial test in 2009.In the 23 intersected wells,the systematic function of SmartMag target hitting performed well with high precision and played an important role in connecting guidance of intersected well.The paper introduced the structural principle and technical parameters,and summed up the application experience and technique of SmartMag system.
