Apparatus for multiple-level successive perforating

The utility model relates to an apparatus for multiple-level successive perforating used for petroleum perforation working, comprising an annular presser 1, a blaster 2, a perforating tool 3, a pressure transmission gun breech 4, a packer 5 and an interlayer oil pipe 6. The annular presser 1 is positioned in an oil pipe 15 which is arranged in a sleeve tube 14; the packer 5 is arranged on the oil pipe 15; the oil pipe 15 is orderly sheathed with the blaster 2, the perforating tool 3 and the pressure transmission gun breech 4; a gun breech 12 is arranged at the bottom of the utility model. The utility model can complete the multiple-level perforation work under any hole conditions, and the retardation initiation orderly carried out in different levels has little damage to the pipe column and the oil well. As the operating cost is low, the utility model can be matched with all types of guns and can conduct the perforating work and the test operation.
