FINITE ELEMENT METHOD FOR PREDICTING DYNAMOMETER CARD OF SLANT STRAIGHT WELL

    Graphical Abstract
    • Abstract
  • The dynamic equation of sucker rod for slant straight well has been established using finite element method.It is suitable for single and multiple stages sucker rod.Being amended,it can be used for sucker rod analysis of any slant well.By this equation,we can calculate the displacement,load and dynamometer diagram at every rod node and any time.This paper also introduces the method to solve the equation,which can save memory of microcomputer.
