Abstract
An initiator head assembly having particular application with a perforating gun assembly. The initiator head assembly includes a body and an electrical contact component with the electrical contact component embedded therein. The initiator head assembly with the embedded electrical contact component is configured as a unitary component, and holds a pressure differential across the top and bottom parts of the initiator head assembly. A method of forming the initiator head assembly is also generally described.
Claims19
An initiator head assembly, comprising:
- a body comprising a head extending from a base, the head including a first surface, a second surface, and an insulating portion extending therebetween, and the base including a first end and a second end, wherein the body is composed of a thermoplastic material and the first end of the base extends from the second surface of the head;
- and
- an electrical contact component comprising an electrically contactable line-in portion and an electrically contactable ground portion, wherein the electrical contact component is positioned proximal to the body,
- wherein the electrically contactable line-in portion is positioned proximal to the first surface, and the ground portion is positioned proximal to the second surface.
An initiator configured for being electrically contactably received within a perforating gun assembly without using a wired electrical connection, comprising:
- a shell comprising a ground portion;
- and
- a wirelessly-connectable selective initiator head assembly, comprising
- a body including a head extending from a base, the head including a first surface, a second surface, and an insulating portion extending therebetween, and the base including a first end and a second end, wherein the body is composed of a thermoplastic material and the first end of the base extends from the second surface of the head, and
- an electrical contact component comprising an electrically contactable line-in portion and an electrically contactable ground portion, the electrical contact component being positioned proximal to the body, wherein
- the base is positioned in the shell.
An initiator head assembly, comprising:
- a body comprising a head extending from a base, the head including a first surface, a second surface, and an insulating portion extending therebetween, and the base including a first end and a second end, wherein the body is composed of a thermoplastic material and the first end of the base extends from the second surface of the head;
- and
- an electrical contact component positioned proximal to the body, the electrical contact component comprising an electrically contactable line-in portion, an electrically contactable ground portion, an electrically contactable line-out portion and an electrical insulation between the line-in portion, the ground portion and the line-out portion.
