Beschreibung
The scientific work is devoted to the study of the work of single-, two-, and three-tier sucker rod columns, which are equipped with both steel and fiberglass rods. The method of determining the coefficients of the extinction of the oscillations of sucker rod columns with the use of dynamograms obtained on a particular well is proposed. The dependence of the dynamical coefficient on the factor of the disorder for different values of the decay factor in the form of amplitude-frequency characteristics is. Recommendations for reducing the dynamic loads on the sucker rod column and preventing resonance in it are formulated. The simulation models of sucker rod columns were created, taking into account their design features, operational parameters of the operation of the downhole sucker rod pump, the features of the interaction of columns of pump-compressor pipes and sucker rods and the laws of the change of effort at the point of their hanging. Obtained values of oscillation decomposition coefficients for the stages formed from fiberglass and steel bars, which enable us to estimate the dynamic behavior of sucker rod column and establish the optimal modes of operation of the down hole.
