Abstract Of The Disclosure A time delay perforating apparatus and method of use. The apparatus includes at least one first and second gun with a time delay device positioned therebetween. The time delay device delays firing of the second gun for a predeter- mined period after firing of the first gun and prevents fluid communication between the first and second guns. The time delay device is positioned in a housing interconnecting the first and second guns and closes off a central opening through the housing. The time delay device includes a body with a primer assembly, a firing pin for detonating the primer assembly, an ignition mix ignited by detonation of the primer assembly, a time delay mix triggered by ignition of the ignition mix, and an explosive disposed in the body. The firing pin is oriented such that it closes off a central opening through the body. The explosive includes a primary explosive triggered by the time delay mix and a secondary explosive triggered by the primary explosive. The time delay device directs its explosive output to fire the second gun.
