Abstract
A non-addressable switch device that is part of a chain of switch devices in a gun string, the non-addressable switch device including a first switch configured to make an electrical connection between an electrical line and another non-addressable switch device of the chain of switch devices; a second switch configured to make an electrical connection between a detonator and the electrical line; and a processor PA connected to the first and second switches and configured to close and open the first and second switches. The processor PA is configured to not use a digital address, and the processor PA is configured to perform one of plural functions based on a corresponding pulse received along the electrical line.
Claims11
A non-addressable switch device that is part of a chain of switch devices in a gun string, the non-addressable switch device comprising:
- a first switch configured to make an electrical connection between an electrical line and another non-addressable switch device of the chain of switch devices;
- a second switch configured to make an electrical connection between a detonator and the electrical line;
- and
- a processor Pa connected to the first and second switches and configured to close and open the first and second switches,
- wherein the processor Pa is configured to not use a digital address, and
- wherein the processor Pa is configured to perform one of plural functions based on a corresponding pulse received along the electrical line.
A chain of a plural of non-addressable switch devices comprising:
- the plural of the non-addressable switch devices electrically connected to each other through an electrical line;
- and
- plural downhole tools, each downhole tool of the plural downhole tools hosting a corresponding non-addressable switch device of the plural of the non-addressable switch devices, wherein each non-addressable switch device of the plural of the non-addressable switch devices includes,
- a first switch configured to make an electrical connection between the electrical line and another non-addressable switch device of the chain of the plural of the non-addressable switch devices;
- a second switch configured to make an electrical connection between a corresponding detonator and the electrical line;
- and
- a processor Pa connected to the first and second switches and configured to close and open the first and second switches,
- wherein the processor Pa is configured to not use a digital address, and
- wherein the processor Pa is configured to perform one of plural functions based on a corresponding pulse received along the electrical line.
