Transportation perforation device of delayed grading detonating pipe

The invention relates to the technical field of pipe conveying perforation, in particular to a delayed graded detonating pipe conveying perforation device. The device comprises an upper connector, a screen pipe, an upper pressure detonating short section, an upper gun connecting connector, an upper perforating gun, a gun tail conversion short section, a continuous oil pipe, a lower pressure detonating short section, a delay detonating short section, a lower gun connecting connector, a lower perforating gun and a gun tail which are sequentially and fixedly installed together from top to bottom. A first impact core shaft and a first impact initiating explosive cake matched with the first impact core shaft are arranged in the upper pressure initiating short section, and the first impact core shaft is fixed in the upper pressure initiating short section through a first shear pin. The device is reasonable and compact in structure and convenient to use, and by arranging the first shear pin and the second shear pin
