FIELD: oil and gas industry.
SUBSTANCE: invention is related to alignment devices, in particular, to devices to be used for alignment of drilling rigs to ensure correct direction of drilling. The laser alignment device intended for use with a drilling rig has an extended drilling rod and a drill head unit comprising at least a pair of laser radiating devices mounted independently at the head unit, at that each laser device can be moved only in one plane and is oriented in essence in opposite directions in regard to each other to set the alignment plane, fasteners to fix the drill head unit to the drill rig and a unit with adjustable length to adjust distance between the head unit and drilling rod.
EFFECT: laser adjustment device is made for alignment of the drilling rod direction in regard to survey marks using the scan plane.
