A tube forming mechanism for application in a tube is provided with a band and clamping mechanism. The clamping mechanism is arranged within the tube, outside of which the band. A system for guiding a bore head is provided, including the tube forming mechanism, a head, mechanism transferring the pressing force to the bore head, and also a curled tube fed from the drum into the wellbore to transfer the pressing force exerted by the pressing mechanism via a mechanism releasably connected to the curled tube. A method of drilling a wellbore is described, wherein a bore head with a drill bit is lowered down the wellbore and pressed against its bottom, simultaneously inserting a tube into to wellbore. For pressing the head with the drill bit, a curled strip tube drawn from a drum is used, wherein the pressing force is applied to the tube via a mechanism releasably connected thereto.
