Systems and methods for coiled tubing drilling

Abstract

Systems and methods presented herein facilitate coiled tubing operations, and generally relate to reduction of shock and vibrations to portions of the coiled tubing string. A device includes a first end configured to be disposed downstream of a bottom hole assembly of a coiled tubing drilling string; a second end configured to be disposed downstream of the first end and upstream of a drive of the coiled tubing drilling string; and a moveable valve configured to move from a first position to a second position to divert at least a portion of drilling fluid flow away from the drive when the drilling fluid flow is greater than a preset flow value or a weight on bit is less than a preset weight value and thereby reduce a rotation rate of the drive.
