Downhole perforating tool with integrated detonation assembly and method of using same

A detonation assembly for a downhole tool positionable in a wellbore penetrating a subterranean formation, the detonation assembly comprising:

• a charge assembly, comprising:
• a charge tube positioned in the downhole tool, the charge tube having a receiver therein;
• and
• shaped charges supported in the charge tube, the shaped charges operatively connectable to the receiver;
• and
• the detonator assembly positionable in the downhole tool, comprising:
• a detonator housing positionable in the downhole tool, the detonator housing having a first connector and a second connector therein;
• a detonator feedthru supported in the first connector;
• a detonator positioned in the detonator housing;
• and
• a trigger positioned in the detonator housing, the trigger communicatively coupled, when in use, between a remote actuator and the detonator, the trigger comprising:
• a switch electrically connected to the detonator feedthru;
• and
• a contact electrically connected to the switch, the contact comprising spring-loaded arms extending from the second connector for electrical contact with the charge assembly.

• a detonator housing positionable in the downhole tool, the detonator housing having a second connector in the detonator housing, the second connector having an offset shape matably receivable into the receiver of the charge tube;
• a detonator positioned about the detonator housing;
• and
• a trigger positioned in the detonator housing, the trigger comprising:
• a switch communicatively coupled, when in use, between a remote actuator and the detonator;
• and
• a contact positioned in the second connector, the contact electrically connected with the receiver of the charge assembly when the second connector is matably connected with the receiver.

A method of assembling a downhole tool, the method comprising:

• assembling a detonator assembly by:
• communicatively connecting a trigger to a detonator;
• positioning the detonator and the trigger in a second connector of a detonator housing;
• positioning the detonator housing in the downhole tool;
• and
• connecting the detonator housing to a charge assembly in the downhole tool by inserting the second connector of the detonator housing into the charge assembly such that a contact of the trigger is urged into electrical contact with the charge assembly.
