滚筒式抽油机加动载荷模拟试验装置设计
|
摘要
针对新型滚筒式抽油机的负载特性,设计了一套抽油机加动态载荷模拟试验装置。采用油缸模拟井筒加动态载荷方案,最大程度还原抽油机的真实加载过程。建立该系统的理论分析模型,采用Adams仿真软件对其进行运动仿真分析,两者的分析结果吻合。应用最小二乘拟合原理,将试验测试的抽油机实时负载数据进行拟合处理,得出实测示功图,并与理论示功图进行对比分析,证明该加载系统能够准确反应抽油机的负载特性,可为新型滚筒式抽油机的设计与改进提供可靠的试验数据。
A set of pumping unit plus dynamic load simulation test device was designed for the load characteristics of the new drum pumping unit. The load scheme applied simulated wellbore plus dynamic load to maximize the true loading process of the pumping unit. The theoretical analysis model of the system was established,meanwhile the motion simulation analysis by Adams simulation software was also performed,and the results of the above two analyses are in agreement.Applying the principle of least squares fitting,the real-time load data of the pumping unit was fitted and processed to obtain the measured force diagram,which to be compared with the theoretical diagram,it proved that the loading system could accurately reflect the load characteristics of the pumping unit,and provided reliable test data for the design and improvement of the new type of drum pumping unit.
