FIELD: oil and gas industry.
SUBSTANCE: in the method for moving a coiled tubing string in a wellbore, a coiled tubing string is moved along the interior of the wellbore, initiating movement along the length of the coiled tubing string and increasing the reach of the coiled tubing along the interior of the wellbore with one or more vibration sources. The initiation occurs by means of one or more vibration sources included in one or more couplers of the coiled tubing units connecting the coiled tubing parts in the coiled tubing string. The source of vibration is a valve.
EFFECT: increased depth of penetration of the coiled tubing string.
