perforatinggunshapedchargeswellbore

The patent describes a reusable perforating gun system that includes a perforating gun with shaped charges, a setting tool, and a downhole plug that can shift between configurations to control fluid communication. A combination switch is integrated to detonate the charges and activate the setting tool based on different firing signals.

Claim 1

1 . A tool string for perforating a tubular string positioned in a wellbore, comprising: a perforating gun comprising one or more shaped charges; a setting tool coupled to the perforating gun; a downhole plug coupled to the setting tool and shiftable between a first configuration in which fluid communication across the plug is permitted and a second configuration in which fluid communication across the plug is restricted in response to activation of the setting tool; and a combination switch coupled to at least one of the perforating gun, the setting tool, and the downhole plug, the combination switch configured to both detonate the one or more shaped charges of the perforating gun in response to receiving a first firing signal and to activate the setting tool to shift the downhole plug from the first configuration to the second configuration in response to receiving a second firing signal. a perforating gun comprising one or more shaped charges; a setting tool coupled to the perforating gun; a downhole plug coupled to the setting tool and shiftable between a first configuration in which fluid communication across the plug is permitted and a second configuration in which fluid communication across the plug is restricted in response to activation of the setting tool; and a combination switch coupled to at least one of the perforating gun, the setting tool, and the downhole plug, the combination switch configured to both detonate the one or more shaped charges of the perforating gun in response to receiving a first firing signal and to activate the setting tool to shift the downhole plug from the first configuration to the second configuration in response to receiving a second firing signal.
