Abstract
According to an aspect, a perforating gun assembly and a detonator assembly is provided. The detonator assembly includes at least a shell, selective detonation, and more than one electrically contactable component that is configured for being electrically contactably received by the perforating gun assembly without using a wired electrical connection, but rather forms the electrical connection merely by contact with at least one of the more than one electrically contactable components. A method of assembling the perforating gun assembly including the detonator assembly is also provided.
Claims8
A wirelessly-connectable selective detonator assembly configured for being electrically contactably received within a perforating gun assembly without using a wired electrical connection, comprising:
- a detonator shell configured for housing a fuse head and an electronic circuit board, wherein the electronic circuit board is connected to the fuse head and is configured to allow for selective detonation of the detonator assembly;
- a detonator head extending from one end of the detonator shell, the detonator head comprising an electrically contactable line-in portion, an electrically contactable line-out portion, and an insulator positioned between the line-in portion and the line-out portion, wherein the insulator electrically isolates the line-in portion from the line-out portion;
- and
- an electrically contactable ground portion,
- wherein the ground portion in combination with the line-in portion and the line-out portion are configured to replace the wired electrical connection and complete the electrical connection merely by contact,
- wherein at least a portion of the detonator shell is configured as the ground portion, and
- wherein the detonator assembly is configured to be electrically contactingly received within a detonator positioning assembly within the perforating gun assembly without using the wired electrical connection, and to selectively receive an ignition signal to fire the perforating gun assembly.
