摘要
近年来，随着水平井在油气勘探和开发中的应用越来越广泛，井完井管柱振动问题逐渐引起人们的关注。本文通过试验研究，探讨了不同气体产量下水平井完井管柱振动的机理。
首先，本文介绍了水平井完井管柱振动的定义和分类，并对振动产生的原因进行了分析。在此基础上，本文提出了试验研究的目标和意义。
接着，本文详细描述了试验的设备和方法，并对试验过程进行了说明。试验中，我们选择了不同气体产量下的水平井进行模拟，记录了管柱振动的频率、振幅和振动形态。
然后，本文对试验结果进行了分析和讨论。首先，我们对不同气体产量下管柱振动的频率和振幅进行了比较，发现气体产量对管柱振动有着明显的影响。随着气体产量的增加，管柱振动的频率和振幅均有所增加。此外，我们还观察到不同气体产量下的管柱振动形态存在差异。通过分析振动形态的变化，我们可以推测出不同气体产量下的振动机理。
最后，本文总结了试验研究的结果，并对未来的研究方向进行了展望。试验结果表明，不同气体产量下水平井完井管柱振动的机理复杂多样，需要继续深入研究。未来的研究可以从改变井筒结构、优化钻井液性质等方面进行探索。

Abstract
In recent years, with the increasing application of horizontal wells in oil and gas exploration and development, the vibration of completion tubulars in horizontal wells has gradually attracted attention. In this paper, through experimental research, the mechanism of completion tubular vibration under different gas production rates in horizontal wells is explored.
Firstly, this paper introduces the definition and classification of completion tubular vibration in horizontal wells, and analyzes the causes of vibration. Based on this, the objectives and significance of the experimental research are proposed.
Secondly, this paper describes the equipment and methods used in the experiments in detail, and explains the experimental process. In the experiments, we simulated horizontal wells with different gas production rates and recorded the frequency, amplitude, and vibration patterns of the tubular vibrations.
Then, this paper analyzes and discusses the experimental results. Firstly, we compare the frequency and amplitude of tubular vibrations under different gas production rates and find that gas production rate has a significant impact on tubular vibrations. With the increase of gas production rate, the frequency and amplitude of tubular vibrations both increase. In addition, we also observe differences in the vibration patterns of tubulars under different gas production rates. By analyzing the changes in vibration patterns, we can infer the vibration mechanism under different gas production rates.
Finally, this paper summarizes the results of the experimental research and looks forward to future research directions. The experimental results show that the mechanism of completion tubular vibration in horizontal wells under different gas production rates is complex and diverse, and further research is needed. Future research can explore from changing wellbore structure, optimizing drilling fluid properties, etc.
