Abstract: According to the operating conditions of the rod string in slant straight wells,a mathematical model for predicting dynamic parameters of sucker rod string in slant straight wells is established.The results of the prediction and its discussion are presented.Taking the rod string as the object of study,a method of computing pumping stroke and speed of walking beam pumping units for slant straight wells is also presented.
