The invention discloses a petroleum drilling machine tubing string automatic processing system. The petroleum drilling machine tubing string automatic processing system is mainly composed of a drill stand, a derrick, an automatic catwalk machine, a power rat hole, a rotary table, a drill stand manipulator, a power slip, an iron roughneck, a power elevator, a racking platform pipe-handling manipulator, a top drive, a winch and a driller integrated control system. After the petroleum drilling machine tubing string automatic processing system is matched to a petroleum drilling machine, automation of all tubing string operation processes of stand column connecting and stand column throwing, individual pipe connecting and individual pipe throwing, drilling, stand pipe storing and stand pipe fetching and the like during the drilling operation process is achieved. According to the invention, the automation degree of the drilling machine is increased, the problem that with respect to the existing drilling tubing string operation mode, many people need to cooperate with one another to work high above the ground, the labor intensity is large, the risk is high, and the efficiency is low is solved, and problems existing in the prior art that the power winch needs to be manually operated, the automatic catwalk machine is low in conveying efficiency and high in energy consumption are cvercome.
