FIELD: oil-and-gas production.
SUBSTANCE: invention relates to a drilling tool for drilling oil and gas wells in seas and oceans, and more specifically to drill pipes. The drilling tool for drilling oil and gas wells in seas and oceans has drill pipes, at the ends of which there are threads. Vessels are attached on the outer side of the drill pipe, with an external pipe of diametre 100-700 mm with stopper plugs and filled with nitrogen gas or inert gas at 0.0001-188.4 MPa pressure. The vessels can be fitted in the top or bottom parts of the drill pipe, or in the top and bottom parts of the drill pipe, or in the top, middle and bottom parts of the drill pipe. The vessels lie along each drill pipe at a distance of 0.5-8 m.
EFFECT: safe operation of the drilling machine due to reduced load on the components of the drilling machine, arising from the weight of the drill column.
