The utility model discloses an inclined shaft azimuthal orientation multilevel pulse benefit increment perforating device, which is adapted to oil and gas well perforating job. The perforating device integrates the advantages of the inclined shaft azimuthal orientation perforator and the multilevel pulse benefit increment perforating device, and employs the novel perforating technologies such as azimuthal orientation perforation, integral benefit increment perforation and multilevel pulse high energy gas fracture. The device perforates the penetrating charge in a direction of the highest permeability by means of the inclined shaft azimuthal orientation perforating technology so as to increase the production power of the oil and gas well by times and meanwhile, it employs the multilevel pulse high energy gas fracturing technology which has strong fracturing capability for the high energy gas, good fracture making capability and high formation fracture closure resistance so as to enhance the yield of the oil gas.
