| Abstract: | The natural frequency of axial vibration of drillstring was analyzed by using finite element method of the ANSYS. Finite element model was established to do research on mode and harmonic response analysis of the natural frequency of axial vibration of drillstring. And according to the analysis,the correlations between each step frequency of axial vibration of drillstring and the length of drillsring in well,the lifting or lowering velocity and time ratio were presented. |
