Wellbore Gun Perforating System and Method

摘要

A wellbore perforating system and method with reliable and safer connections in a perforating gun assembly is disclosed. The system/method includes a gun string assembly (GSA) deployed in a wellbore with multiple perforating guns attached to plural switch subs. The perforating guns are pre-wired with a cable having multi conductors; the multi conductors are connected to electrical ring contacts on either end of the perforating guns. The switch subs are configured with electrical contacts that are attached to the electrical contacts of the perforating guns without the need for manual electrical connections and assembly in the field of operations. The system further includes detonating with a detonator that is positioned upstream of the perforating gun. The detonator is wired to a switch that is positioned downstream of the perforating gun.
