Configuration Research of Centering Device Effected by Viscoelastic Fluid
Journal Title: Scholars Journal of Engineering and Technology - Year 2015, Vol 3, Issue 3
Abstract
The polymer flooding can improve the oil production at the late stage of oilfield development but this viscoelastic behavior of the polymer solution will cause sucker rods eccentric wear and break off., which can shorten the cycle of pump inspection. In this paper, we studied the influence of those stress factors on the rod according to the force analysis of rod during down stroke, established mechanical model, and finded out advisable interspacing that centering device should be arranged by using MATLAB to program and calculate. In this way can extend the cycle of pump inspection, and can lay a foundation for further investigation. Keywords: polymer flooding, normal force, centering device, anti-eccentric, viscoelasticity, MATLAB
