摘要
水平井钻柱动力学是水平钻井工程的重要理论基础。通过水平井钻柱动力学分析可以很好地了解水平井钻柱的运动状态,科学地预测和控制井眼轨迹,揭示钻柱失效的动力学机理。就目前国内外水平井钻柱动力学研究现状进行了分析研究。综合研究表明,目前水平井钻柱动力学理论研究较欠缺,已滞后于实际工程应用,研究的内容也侧重钻柱动力学的某一方面。指出了今后水平井钻柱动力学研究的方向,提出了用全井钻柱系统动力学模型来研究水平井钻柱动力学。
Drill string dynamics is an important basic theory in horizontal well drilling engineering.Analysis of drill string dynamics gives a better understanding of movement of the string in horizontal well for scientific forecast and control of well trajectory and reveals the mechanism of drill string failure.Analysis of the current situation in the study of drill string dynamics in horizontal well at home and abroad indicates that the theoretical study has fallen behind practical engineering application and the study stresses on some certain aspect of drill string dynamics.This paper pointes out the research direction of horizontal well drill string dynamics and proposes to conduct the research by using a dynamics model for the whole drill string system.
