油气井钻柱粘滑振动研究进展

摘要

Stick-slip vibration is one of the major causes for hole quality reduction,shorter drilling tool lifespan,drilling efficiency decrease,seriously affecting the drilling cost and completion peri-od.The complex situations in the process of drilling result in the slow progress in this aspect,rare research breakthrough recently.The recent advances are outlined in stick-slip vibration of the drill string in three areas:theoretical analysis,experiment research and analogue simulation.The main research direction,methods and existing problem in the progress are introduced,which will pro-vide reference and guidance for further research.%粘滑振动是造成深井钻井井身质量下降、钻具寿命减短、钻进效率降低的主要原因之一，严重影响到钻井成本和完井周期。复杂的钻井环境也使得钻柱粘滑振动的研究进展缓慢，突破性成果较少。从理论分析、现场及室内试验研究和模拟仿真3个方面对钻柱粘滑振动的国内外研究现状进行阐述。介绍了当前关于钻柱粘滑振动的主要研究方向、方法以及研究过程中存在的问题，为后续开展钻柱粘滑振动的深入研究提供借鉴和指导。
