Abstract:The application of the continuous carbon fiber sucker rod pumping system is successful preliminarily in the oilfields of our country, and has shown great economic value to promote to large area. A continuous carbon fiber sucker rod busywork unit is developed in which the sucker rod lifting (setting down) and the sucker rod coiling are driven separately. In order to prevent the busywork unit to roll, a mathmodel which included 242 nodes and 228 elements was set up for the finite element analysis (FEA), and solved by using ANSYS FEA software. By calculation and analysis, it is proved that the vehicle will not roll over in routine operation, and its overall structural design is reasonable. And this designed model has certain value to further research.
