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.
Claims20
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.
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 based is positioned in the shell.
A method of making an initiator head assembly, comprising:
- forming an electrical contact component comprising an electrically contactable line-in portion and an electrically contactable ground portion;
- forming a body as a unitary component around the electrical contact component to seal the electrical contact component against pressure leakage across the body, wherein the body includes a head extending from a base, the head including a first surface and 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.
