Abstract
An initiator head assembly may include a body and an electrical contact component positioned proximal to the body. The body may include a head extending from a base, and a platform extending from the head, and the body may be injection molded as a unitary component. The electrical contact component may include a line-in portion positioned proximal to the platform and a ground portion positioned proximal to the head. The electrical contact component may be formed integrally with the body such that it is anchored in a fixed position in the body. An initiator for a perforating gun assembly may include the initiator head assembly and a shell coupled to the initiator head assembly.
Claims20
An initiator head assembly comprising:
- a body comprising a first surface, a second surface, and an insulating portion extending between the first surface and the second surface;
- and
- an electrical contact component comprising an electrically contactable line-in portion positioned proximal to the first surface, and an electrically contactable line-out portion positioned proximal to the second surface, wherein
- the initiator head assembly is configured to complete a wireless electrical connection by being electrically contactably received within a perforating gun assembly without using a wired electrical connection, and
- the initiator head assembly is configured for detonating one or more downstream components of the perforating gun assembly.
A wirelessly connectable initiator head assembly, comprising:
- a body including a head extending from a base, wherein the head includes a platform extending from a first surface of the head away from the base, and the base extends from a second surface of the head;
- and
- an electrical contact component at least partially embedded within the body, the electrical contact component comprising:
- an electrically contactable line-in portion positioned adjacent a top surface of the platform;
- a line-in contact extending from the line-in portion through the head and the base;
- an electrically contactable ground portion positioned adjacent the second surface of the head;
- and
- a ground contact extending from the ground portion through the base, wherein
- the electrical contact component is held in a fixed position relative to the body,
- the initiator head assembly is configured to complete a wireless electrical connection by being electrically contactably received within a perforating gun assembly without using a wired electrical connection, and
- the initiator head assembly is configured for detonating one or more downstream components of the perforating gun assembly.
An initiator head assembly, comprising:
- a body, comprising a head extending from a base, wherein the head includes a first surface, a second surface, an insulating portion extending therebetween, and a platform extending from the first surface away from the base, and wherein 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 positioned proximal to the platform, and an electrically contactable ground portion positioned proximal to the second surface, wherein the insulating portion electrically insulates the line-in portion and the ground portion.
