摘要
针对抽油井系统工作状况 ,以油井生产管柱为研究对象 ,建立了研究油管柱振动特性的力学模型。推导出了描述油管柱振动规律的波动方程、固有频率方程、油管柱振动位移方程等数学模型。研究了引起油管柱产生共振的激励频率与油管柱固有频率的关系等。对抽油井生产过程中油管柱的振动有了新的较全面的认识。
Based on the working condition of the pumping well system, through the study on the production string of the oil well, a mechanical model for studying the vibration characteristics of tubing string has been established. From which the mathematical models like wave equation, natural frequency equation and tubing string vibration displacement equation used to describe the tubing string vibration laws have been educed. This paper also studies the relationship between the exciting frequency that can cause the tubing string to resonate and the natural frequency of the tubing string.
