Abstract
An apparatus for detonating an explosive body associated with a downhole tool includes a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated; and a funnel configured to detonate the explosive body associated with the downhole tool by using a single high-order output. The funnel has a body that includes: a plurality of input openings, each input opening positioned next to an associated initiating explosive body to receive the generated high-order input, a single output opening, and a flow path connecting the plurality of input openings with the single output opening.
Claims13
An apparatus for detonating an explosive body associated with a downhole tool, comprising:
- a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated;
- and
- a funnel configured to detonate the explosive body associated with the downhole tool by using a single high-order output, the single high-order output being formed of at least one of the generated high-order inputs, the funnel having a body that includes:
- a plurality of input openings, each input opening positioned next to the associated initiating explosive body to receive the generated high-order input, each associated initiating explosive body being completely external to the funnel,
- a single output opening being oriented to direct the single high-order output to the explosive body associated with the downhole tool;
- and
- a flow path connecting the plurality of input openings with the single output opening.
An apparatus for detonating an explosive body associated with a downhole tool, comprising:
- a plurality of side-by-side firing heads, each firing head including an initiating explosive body generating a high-order input when detonated;
- a funnel having a body that includes:
- a plurality of input openings, each input opening being positioned next to an associated initiating explosive body that is completely external the funnel, each input opening being positioned to receive the generated high-order input, wherein each input opening is in communication with an associated passage,
- a juncture connecting the associated passages of the plurality of input openings,
- a single output passage having a first end connected to the juncture and a second end, and
- a single output opening formed at the second end of the single output passage, wherein the plurality of input openings, the juncture, and the single output passage cooperate to form a single high-order output from of at least one of the generated high-order inputs, the second end oriented to direct the single high-order output to the explosive body.
An apparatus for detonating a downhole tool, comprising:
- an explosive body configured to detonate the downhole tool;
- a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated;
- and
- a funnel separating the explosive body and the plurality of firing heads, the funnel being configured to detonate the explosive body associated with the downhole tool by using a single high-order output, the single high-order output being formed of at least one of the generated high-order inputs, the funnel having a body that includes:
- a plurality of input openings, each input opening positioned next to the associated initiating explosive body to receive the generated high-order input
- a single output opening from which the single high-order output exits, and
- a flow path connecting the plurality of input openings with the single output opening.
