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.

摘要： A technique facilitates controlled detonation in well environments and other types of environments. Electronics for controlling detonation of a pellet of explosive material are mounted on a structure, such as a circuit board. The pellet is operatively coupled with the electronics and positioned to extend outwardly from the structure. Another explosive component is arranged across the pellet at a predetermined angle, e.g. a right angle, with respect to a longitudinal axis of the pellet. In well applications or other applications utilizing shaped charges, the explosive component may be coupled to the shaped charge via a detonator cord.

摘要： Detonation control modules and detonation control circuits are provided herein. A trigger input signal can cause a detonation control module to trigger a detonator. A detonation control module can include a timing circuit, a light-producing diode such as a laser diode, an optically triggered diode, and a high-voltage capacitor. The trigger input signal can activate the timing circuit. The timing circuit can control activation of the light-producing diode. Activation of the light-producing diode illuminates and activates the optically triggered diode. The optically triggered diode can be coupled between the high-voltage capacitor and the detonator. Activation of the optically triggered diode causes a power pulse to be released from the high-voltage capacitor that triggers the detonator.

摘要： A tool activation system and method includes receiving an authorization code of a user to verify access rights of a user to activate the tool. In one example, the authorization code is receive from a smart card. The environment around the tool, which can be in a wellbore, for example, is checked. In response to the authorization code and the checking of the environment, activation of the tool is enabled.
