Abstract
A detonator module provides for the use of a wide range of different addressable switches for use in perforating guns. The detonator module permits pre-assembly of a desired addressable switch and conforms the electrical connectivity to a particular perforating gun. In this manner, nearly any addressable switch can be used from any manufacturer despite having different sizes or wiring layouts. The pre-assembled detonator module can be safely shipped due to a safety shunt that can be removed on site prior to installation into a perforating gun. In one sense, the detonator module permits conformance of multiple different types of addressable switches to a particular type or model of perforating gun, permitting flexible choice of addressable switch for a particular project.
Claims20
A detonator module, comprising:
- a housing defining a compartment to receive an addressable switch within the compartment;
- a first electrical pad positioned at an uphole end of the housing to communicate with at least one uphole assembly or control system;
- and
- a second electrical pad positioned at a downhole end of the housing for communicating with any downhole assembly in a wellbore.
An detonator module, comprising:
- a housing having an uphole end, a downhole end and two opposing sides disposed between the uphole end and the downhole end, the housing sized to be insertable within a perforating gun, the housing defining a compartment to accept an addressable switch therewithin, the addressable switch for controlling detonation of a perforating gun;
- a first printed circuit board (PCB) to electrically connect the addressable switch with uphole assemblies in a wellbore or to surface equipment;
- a second PCB to connect the addressable switch with downhole assemblies in a wellbore;
- and
- a grounding element located on the housing and connected to at least one of the first PCB and the second PCB, the detonator module insertable into a perforating gun, the grounding element contactable with the perforating gun.
A method of providing a detonator module comprising:
- providing a housing that defines a compartment to receive an addressable switch within the compartment;
- and
- positioning at least one printed circuit board (PCB) having a first electrical pad thereon at an uphole end of the housing to communicate with at least one uphole assembly or a control system, and the at least one PCB having a second electrical pad thereon at a downhole end of the housing for communicating with any downhole assembly, the first electrical pad passing communications from the at least one uphole assembly or a control system to the second electrical pad.
