| 摘 要： | 结合油田生产实际,对抽油杆柱与油管系统的磨损介质类型和磨损机理进行了分析,建立了抽油杆三维力学综合分析模型,利用VisualBasic6.0语言和Matlab6.0语言开发了相应的仿真分析软件系统,并进行了三维井眼轨迹对抽油杆柱受力变形的影响研究。利用该软件系统,可以确定抽油杆柱与油管严重偏磨点的位置。使用新型抗摩擦接箍,可使定向井抽油杆柱偏磨的程度大幅度下降,从而节省修井时间并提高油井寿命。

| Abstract: | Based on the practical situation of oilfield, the medium type and mechanism of abrasion between sucker rod string and tubing were analyzed. A 3D mechanics calculation model for analyzing sucker rod string was established. The relative software was programmed with VB 6.0 and Matlab 6.0 language. The influence of 3D wellbore trajectory on the stress and deformation of sucker rod string was studied with this software. The serious abrasion position can also be predicted with this software. By using new anti-abrasion joint in the serious abrasive position, the degree of uneven abrasion between sucker rod string and tubing can be largely decreased. The new anti-abrasion joint can prolong the production life of oil well and save the time of well workover. |
