Abstract
In general, in one aspect, embodiments relate to an electrical contact that includes a contact plate, a support plate, and three or more bends disposed between the contact plate and the support plate to counteract a force applied to the contact plate when engaged by a contact pin, where the electrical contact is configured to convey a detonating signal through an electrical feedthrough extending through at least a bulkhead of two or more perforating guns.
Claims17
An electrical contact comprising:
- a contact plate;
- a support plate;
- three or more bends disposed between the contact plate and the support plate to counteract a force applied to the contact plate when engaged by a contact pin, wherein the electrical contact is configured to convey a detonating signal through an electrical feedthrough extending through at least a bulkhead of two or more perforating guns, wherein the three or more bends comprise three or more folds that do not extend past a diameter of the support plate to keep the contact plate axially located during deformation from contact with the contact pin;
- and
- two or more exterior fins for maintaining axial contact with the contact pin, wherein the two or more exterior fins are disposed about the support plate, wherein an outer diameter of the support plate and the two or more exterior fins is greater than a longitudinal distance between two folds.
2 more elements
A method comprising:
- disposing two or more perforation guns into a wellbore extending into a subterranean formation, wherein the two or more perforation guns are electrically coupled by an electrical contact and a contact pin, the electrical contact comprising:
- a contact plate;
- a support plate;
- three or more bends disposed between the contact plate and the support plate to counteract a force applied to the contact plate when engaged by the contact pin, wherein the three or more bends comprise three or more folds that do not extend past a diameter of the support plate to keep the contact plate axially located during deformation from contact with the contact pin;
- and
- two or more exterior fins for maintaining axial contact with the contact pin, wherein the two or more exterior fins are disposed about the support plate wherein an outer diameter of the support plate and the two or more exterior fins is greater than a longitudinal distance between two folds.
3 more elements
A method of assembling a perforating gun string, the method comprising:
- securing a plurality of perforating charges at different positions and firing orientations along a charge carrier;
- securing an end alignment between the charge carrier and a bulkhead, the end alignment and bulkhead comprising an electrical feedthrough;
- disposing an electrical contact within the electrical feedthrough, the electrical contact comprising a contact plate, a support plate, three or more bends disposed between the contact plate and the support plate, wherein the three or more bends comprise three or more folds that do not extend past a diameter of the support plate to keep the contact plate axially located during deformation from contact with the contact pin, and two or more exterior fins for maintaining axial contact with the contact pin, wherein the two or more exterior fins are disposed about the support plate, wherein an outer diameter of the support plate and the two or more exterior fins is greater than a longitudinal distance between two folds;
- engaging the contact plate with a contact pin, wherein the electrical contact and the contact pin are configured to transmit a detonation signal between a first perforating gun and a second perforating gun for detonating the perforating gun string.
