Dynamic Instability of Slender Sucker Rod String Vibration Characteristic Research

Abstract:

The vibration of oil well sucker rod is one of the main reasons that cause breaking and disengaging to the pumping well. According to vibration mechanics theory and nonlinear theory, building the vibration mechanics model of the subsurface rod system, combined with finite element theory, using spatial beam element to establish the finite element of the rod. And according to the interface ingenerating conditions, adopt augmented Lagrange multiplier method to embed it into the finite element equations, tracing the contact friction state of the rod and tubing, to obtain the rod vibration characteristics and the contact state with the tubing during work process, to analyze the change law and influencing factors, providing the theoretical support to the vibration control of the rod.
