摘要：

Questions related to the study of the transmitted pressure vibrations of fluid being injected into development and injection wells by means of a tubing string are considered. Mathematical models of a tubing string in pulse injection of fluid and in installation of the device for the purpose of damping hydraulic impacts are described. An expression by means of which the required parameters of effective damping of vibrations may be determined from the standpoint of maintaining the service life of the tubing string is obtained through transformations of the wave equations. A graphical dependence of the amplitude of the displacement on the ratio of the frequency of the vibrations of a tubing string is presented from calculations. © 2017, Springer Science+Business Media, LLC.
