Wireline conveyed firing mechanism for well perforating gun
A replaceable firing mechanism is described for a subterranean well perforating gun which consists of a first hollow housing attachable to the top end of a perforating gun and having a thin walled top end surface closing the bore of the hollow housing; a detonatable firing element positioned within the first hollow housing and operatively connected to the perforating gun. A wireline carried firing assembly includes a second housing having a thin walled bottom end surface; an impact detonatable primer fixedly mounted in the housing; a hammer axially slidable in the second housing between a remote and contiguous position relative to the primer; a wireline attached member fixedly secured to the hammer; means secured to the wireline attachable member for detachably engaging the first and second hollow housings. The solid end of the second housing may be positioned in vertical abutment to the top end surface of the first housing; and means for transferring the detonating energy of the primer to the detonatable firing element, whereby a downward impact force on the wireline attachable member will sequentially detonate the primer, the detonatable firing element and the perforating gun.
