Abstract
According to an aspect an initiator head assembly (10, 110) is provided having particular application with a perforating gun assembly, in particular for oil well drilling applications. The initiator head assembly includes a body (20, 120) and an electrical contact component (40, 140) with the electrical contact component embedded therein. In another aspect, the initiator head assembly with the embedded electrical contact component is configured as a unitary component and also to hold a pressure differential across the top and bottom parts of the initiator head assembly. In an aspect, the method of forming the initiator head assembly is also generally described.
Claims20
An 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, the base including a first end and a second end;
- and
- an electrical contact component comprising an electrically contactable line-in portion, and an electrically contactable ground portion,
- wherein the electrical contact component is integrally formed with the body such that the line-in portion of the electrical contact component is positioned proximal to the first surface of the head of the body and the ground portion of the electrical contact component 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 and a second surface, and an insulating portion extending therebetween, the base including a first end and a second end (34), and an opening extending at least partially therebetween, wherein the body is configured as a unitary component;
- and
- an electrical contact component comprising an electrically contactable line-in portion, an electrically contactable line-out portion, and an electrically contactable ground portion,
- wherein the line-in portion of the electrical contact component is positioned proximal to the first surface of the head of the body and the line-out portion of the electrical contact component is positioned proximal to the second surface, and the ground portion of the electrical contact component is positioned proximal to the opening of the base of the body,
- wherein the ground portion of the electrical contact component is positioned in electrical contact with the ground portion of the shell.
An initiator configured for being electrically contactably received within a perforating gun assembly without using a wired electrical connection, comprising:
- a shell;
- and
- a wirelessly-connectable initiator head assembly, comprising:
- a body including a head extending from a base, the head including a first surface and a second surface, and an insulating portion extending therebetween, the base including a first end and a second end, wherein the body is configured as a unitary component;
- and
- an electrical contact component comprising an electrically contactable line-in portion, and an electrically contactable ground portion,
- wherein the line-in portion of the electrical contact component is positioned proximal to the first surface of the head of the body and the ground portion of the electrical contact component is positioned proximal to the second surface.
