FIELD: drilling of soil or rock.
SUBSTANCE: group of inventions relates to drilling. Drilling system with several fluid media, made with possibility of connection with end of drill string, made with possibility to provide separate and independent flow of first fluid medium and second fluid medium, comprises a hammer disposed such that when the drill string is held, the first fluid medium flowing through the drill string can drive the hammer, motor arranged such that, when the drill string is held, the second fluid flowing through the drill string can flow through the motor and actuate it. Motor is connected to the hammer and is intended for hammer rotation when the second fluid medium flows through the motor. Drilling system is designed to provide flow of second fluid medium into well drilled by means of drilling system.
EFFECT: providing optimization and efficiency of drilling system and method.
