Abstract
According to an aspect, a perforating gun assembly and a detonator assembly are provided. The detonator assembly includes at least a shell, 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. According to an aspect, the detonator assembly includes a selective detonator assembly. A method of assembling the perforating gun assembly including the detonator assembly is also provided.
Claims15
A wireless detonator assembly configured for being electrically contactably received within a perforating gun assembly without using a wired electrical connection, comprising:
- a shell configured for housing components of the detonator assembly;
- more than one electrical contact component, wherein at least one of the electrical contact components extends from the shell and further wherein the electrical contact component comprises an electrically contactable line-in portion, an electrically contactable line-out portion and an electrically contactable ground portion, the ground portion in combination with the line-in portion and the line-out portion being configured to replace the wired electrical connection to complete an electrical connection merely by contact;
- 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
- means for selective detonation housed within the shell,
- wherein the detonator assembly is configured for electrically contactably forming the electrical connection merely by the contact.
A perforating gun assembly, comprising:
- a wirelessly-connectable selective detonator assembly configured for being electrically contactably received within the perforating gun assembly without using a wired electrical connection, the detonator assembly comprising:
- a shell configured for housing components of the detonator assembly;
- more than one electrically contactable component, wherein at least one of the electrical contact components extends from the shell and further wherein the electrical contact component comprises an electrically contactable line-in portion, an electrically contactable line-out portion, and an electrically contactable ground portion, the ground portion in combination with the line-in portion and the line-out portion being configured to replace the wired electrical connection to complete an electrical connection merely by contact;
- 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
- means for selective detonation of the detonator assembly,
- wherein the means for selective detonation is housed within the shell, and the detonator assembly configured for electrically contactably forming the electrical connection merely by the contact and without the need of manually and physically connecting wires.
A method of assembling a perforating gun assembly without using a wired electrical connection, comprising:
- positioning a wirelessly-connectable selective detonator assembly within the perforating gun assembly, wherein the detonator assembly comprises:
- a shell configured for housing components of the detonator assembly;
- more than one electrically contactable component, wherein at least one of the electrical contact components extends from the shell and further wherein the electrical contact component comprises an electrically contactable line-in portion, an electrically contactable line-out portion, and an electrically contactable ground portion, the ground portion in combination with the line-in portion and the line-out portion being configured to replace the wired electrical connection to complete a wireless electrical connection merely by contact;
- 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
- means for selective detonation of the detonator assembly,
- electrically contactingly connecting the detonator assembly such that the detonator assembly electrically contactably forms the wireless electrical connection merely by the contact and without the need of manually and physically connecting wires.
