FIELD: construction.
SUBSTANCE: system for well drilling comprises base, mast, injector of flexible pipe and starter tip mounted on the mast so that it may move along it. At the same time starter tip provides for transfer of rotation torque for connection and disconnection of string components and may be used to drill with composite pipes. At the same time starter tip may be used to prevent unwanted rotation of drilling string in process of drilling, using well engine with the help of rotary cartridge capable of blocking. Drilling method is also disclosed with application of proposed system.
EFFECT: improving drilling plant operation reliability.
