Research of the pulsating flow of drilling fluid in the drill string

open access: yesTechnology audit and production reserves, 2022
The object of research is the pulsating flow of drilling fluid in the drill string. One of the most problematic places is pressure loss due to friction forces distributed along the length of the flow and concentrated in its nodes (threaded joints and pipe bends).
