| 摘 要： | 根据实际井眼轨迹的特征及系统动力学理论建立了抽油杆柱在实际井眼中的动态仿真模型。应用有限差分法对不同抽油杆柱组合在实际井眼中各个节点的三维受力特征及位移做出了较详细的分析,在此基础上利用模块化编程技术开发了三维井眼条件下杆柱设计、力学分析及偏磨点位置预测软件,并对抽油杆柱组合的合理性、杆柱的受力特征、偏磨状况等进行了仿真。对现有抽油杆柱系统进行分析并提出优化方案。软件计算结果与实验井测试数据一致,体现了软件有较好的预测效果和较高的现场实用价值。

| Abstract: | A three-dimensional dynamic simulation model of rod string in actual borehole was established based on the characteristics of actual well track and system dynamics theory.Based on this new model,a Design and Analysis system for Rod String(DARS software) was developed,which could be used to design the structure of rod string,and to predict the position of eccentric wear.A comparison of software predicted results with measured data was made,and a good consistency was got.Numerous examples are presented to demonstrate the application value and prediction effect of the DARS. |
