在实际的钻井中钻柱不可避免的产生振动，振动包括纵向振动、横向振动、扭转振动以及他们的耦合振动。钻柱强烈的共振可能造成严重的钻井事故，从而增加了钻井难度和风险，甚至带来巨大的经济损失。
本文分别对纵向、横向、扭转三种振动进行了理论分析，总结了三种振动的力学规律，建立了力学模型，推导出了振动频率方程，从而得出了钻柱振动的共振规律。并以大庆油田升深7井1600米井深为例，应用ANSYS软件建立了基于APDL语言的钻柱参数化有限元仿真模型，该模型具有较强的实用性和通用性，极大地提高了分析和研究的效率，并为进一步的分析和研究奠定了良好基础。论文中所建立的有限元模型，考虑了钻井液的压力和浮 力等影响因素，与已有的其它钻杆柱有限元模型相比，仿真程度有很大的提高。文中对钻柱纵向振动、横向振动和扭转振动的分析结论，可以为避免钻柱共振提供可靠的参考价值。扭转振动的分析结果还可以为不同类型钻头临界转速的确定提供计算依据。通过三种振动频率的对比，还发现纵向振动和扭转振动的固有频率范围有重叠的部分，这一点为研究钻柱的共振破坏、强度破坏、减振器的安装位置等问题提供了依据。通过分析对比可以发现，钻柱纵向振动和横向振动各阶最大位移的节点位置很接近，所以在此节点附近钻柱最容易产生破坏，这可以为工程实际中的设计、生产和应用提供有意义的参考价值。

In the actual drilling is inevitable in the selection of drill string vibration, vertical vibration, including vibration, lateral vibration, torsional vibration, as well as their coupled vibration. Drillstring resonance strong drilling may result in serious accidents, thus increasing the difficulty and the risk of drilling, and even bring about huge economic losses.
In this paper, on the vertical, horizontal, reversing three theoretical vibration analysis, summed up the three laws of mechanical vibration, the establishment of a mechanical model, derived from the vibration frequency equation drillstring so as to arrive at the laws of vibration resonance. And Daqing oil fields or deep wells 1600 meters depth 7 as an example, the application of ANSYS software APDL language based on the parameters of the drill string of finite element simulation model has a strong practicality and versatility, which greatly improved the analysis and the efficiency of research and for further analysis and research has laid a good foundation. Paper established finite element model, taking into account the pressure of drilling fluid and the impact of factors such as buoyancy, and other existing finite element model of pipe column compared to the degree of simulation greatly improved. In this paper, vertical drillstring vibration, lateral vibration and torsional vibration analysis of the conclusions, you can drill string in order to avoid resonance to provide a reliable reference value. Torsional vibration analysis of different types can also drill to determine the critical speed calculated on the basis of the provision. Through the comparison of the three vibrational frequencies, also found that the longitudinal vibration and torsional vibration natural frequency of the overlapping part of the scope of this study drillstring resonance destruction, damage strength, the installation location, such as shock absorber to provide a basis. Can be found through the analysis of contrast, vertical drillstring vibration and lateral vibration of the maximum displacement of the bands is very close to the location of the node, so nodes in the vicinity of the drill string the most prone to damage, which can be practical for engineering design, production and application of the provision of meaningful the reference value.
