High-resistance electric detonator for oil-gas well perforation

The utility model discloses a large-resistance electric detonator for oil and gas well perforation. Detonator, a reinforcing cap is arranged in the detonator; an initiating explosive and a high explosive are sequentially filled between the reinforcing cap and the bottom of the detonator; a fire transmission hole is formed in the top of the reinforcing cap; an electrode plug is clamped in the upperend of the detonator; a packaging resistor with the resistance value not smaller than 50 ohms is arranged in the electrode plug, two first wires are arranged in the packaging resistor, two second wires are externally connected to the upper end of the electrode plug, each second wire is connected with one end of the corresponding first wire, and the other ends of the two first wires are connectedwith an ignition head. The large-resistance electric detonator for oil and gas well perforation can meet the requirement that the resistance value is not less than 50 ohms on the basis of simple product structure, small size a
