Device and method for positioning a detonator within a perforating gun assembly

A perforating gun assembly comprising a detonator positioning device and a wireless detonator, the assembly comprising:

• a detonator;
• and
• a detonator positioning device for positioning the detonator in a perforating gun assembly, the device comprising:
• a multi-part cylindrical body comprising at least a first part and a second part, wherein the first part is removably connected to the second part of the cylindrical body to form an assembled cylindrical body, each of the first part and the second part including at least a first portion and a second portion, the assembled cylindrical body comprising an open end, a closed end, and a central bore adapted for receiving the detonator, the central bore extending along at least some of a length of the assembled cylindrical body, and the central bore including an enlarged bore portion adjacent the open end of the assembled cylindrical body,
• a plurality of arms extending toward the open end of the assembled cylindrical body and at least partially enclosing the enlarged bore portion of the central bore, each of the plurality of arms comprising a retainer adapted to retain a detonator head of the detonator when positioned within the enlarged bore portion of the central bore, and
• a plurality of legs extending from the assembled cylindrical body and toward the closed end of the assembled cylindrical body, each of the plurality of legs comprising a protrusion extending away the assembled cylindrical body and adapted for positioning the assembled cylindrical body in the perforating gun assembly.

A method of assembling a perforating gun assembly while using a semi-wired electrical connection, the method comprising:

• positioning a detonator positioning device within the perforating gun assembly, the detonator positioning device comprising a central bore;
• positioning a ground connector biasing member at a base of the central bore;
• positioning a line-out connector biasing member at a base of an enlarged portion of the central bore;
• positioning a terminal for receiving a single line-out wire adjacent the line-out connector biasing member;
• positioning a wireless detonator within the central bore such that a housing of the detonator extends along at least a portion of the central bore and a ground portion of the housing electrically contacts the ground connector biasing member;
• and
• positioning a head of the detonator within the enlarged portion of central bore such that a line-out portion of the detonator electrically contacts the terminal, and a line-in contact-initiating pin electrically contacts a line-in portion of the detonator.
