FIELD: oil and gas industry.
SUBSTANCE: device for drilling of a well and its operation comprising lifting pipes, a drill-collar string, a hydraulic downhole motor and a chisel. The device is additionally equipped with a slag and metal trap, an upper centrifugal pump to supply a fluid from a wall to a well head with partial liquid intake from the first flow and the lower centrifugal pump to create a hydraulic force to operation of a hydraulic downhole motor.
EFFECT: combined processes of drilling and oil production and increased efficiency of bed opening technology and subsequent oil production.
