FIELD: oil industry, in particular, technology for reducing vibrations of tubing pipes equipped with centrifugal electric down-pumps. ^ SUBSTANCE: reduced level of body vibration of tubing pipes in low frequency spectrum. Method for reducing vibrations of tubing pipes, created by noisy flow of liquid above centrifugal electric down-pump, includes placing in an adapter one or a set of quarter-wave resonators and installation thereof into tubing pipes above centrifugal electric down-pump. ^ EFFECT: increased efficiency. ^ 2 dwg |
