为探究储气库井注采过程管柱非线性振动特性，获得储气库井管柱在井筒内的动力特性和频域特征。首先，根据储气库井筒结构特点建立储气库井管柱非线性振动分析方法，通过数值求解得到管柱非线性的数学方程；其次，根据振动模型建立ANSYS仿真模型，模拟分析管柱的固有特性并与数学模型结果进行对比，同时对储气库井管柱进行瞬态动力学响应分析，得到管柱振动效果变化规律；最后，结合现场工况搭建储气库井管柱振动实验研究装置，设计振动信号数据采集终端，通过注气过程管柱非线性振动实验得到振动特征数据。以实际储气库井J03-H1为例，分析注气过程管柱压力、管壁速度和幅值等振动效果变化规律。结果表明：同一生产条件下所建模型计算结果与ANSYS仿真结果基本一致；随着管柱设计的增长，环空约束对管柱固有特性影响作用较大；低频压力波动是诱发管柱振动的重要激励源；随着注气量的增加，各段管柱振动效果变化明显，呈周期性变化，其中近注气口段和井斜段是储气库井管柱产生振动的高发区域，在管柱安全生产设计和运行时应做出相应的安全措施。
Abstract
In order to explore the nonlinear vibration characteristics of the pipe string in a gas storage well injection process, the dynamic characteristics and frequency domain characteristics of the string in the wellbore were obtained.Firstly, according to the structural characteristics of the gas storage wellbore, a nonlinear vibration analysis method of the gas storage well string was established, and the mathematical equation of the nonlinearity of the tubular string was obtained by numerical solution.Secondly, an ANSYS simulation model was established according to the vibration model to simulate the inherentity of the r string.The characteristics were compared with the results of the mathematical model.Meanwhile, the transient dynamic response analysis of the gas storage well string was carried out to obtain the vibration effect of the column.Finally, the vibration of the gas string of the gas storage well was constructed in combination with the site conditions.An experimental device was designed as the vibration signal data acquisition terminal, and the vibration characteristic data were obtained through the nonlinear vibration experiment of the pipe string during the gas injection process.Taking the actual gas storage well J03-H1 as an example, the variation of vibration effect such as column pressure, wall speed and amplitude of gas injection process was analyzed.The results show that the model calculation results under the same production conditions are basically consistent with the ANSYS simulation results.With the increase of the column design, the annulus constraints have a great influence on the inherent characteristics of the column; low frequency pressure fluctuation is the important factor to induce the column vibration.Excitation source; with the increase of gas injection volume, the vibration effect of each column was obviously changed, which changes periodically.The near gas injection section and the well inclined section are the high-incidence areas where the gas storage well string generatesvibration, and the column is safe.Corresponding safety measures should be taken during production design and operation.
