Abstract
In one aspect of the present invention, a downhole tool assembly comprises electrical connectors disposed proximate an upper end and a lower end of the tool, switches to selectively allow or disallow electrical continuity between the electrical connectors, and a microprocessor in electrical communication with the electrical connectors and the switches.
Claims20
A downhole tool assembly, comprising;
- first and second electrical power connectors disposed in a first section and a second section of the downhole tool, each electrical power connector associated with at least one power source;
- an electrical tool instrument disposed intermediate the connectors;
- switches intermediate the electrical connectors to selectively allow or disallow power to the electrical tool instrument;
- and
- a microprocessor in electrical communication with the electrical connectors and the switches.
2 more elements
A method for downhole power distribution, comprising:
- providing a downhole tool intermediate adjacent downhole assemblies;
- electrically coupling the downhole tool to the adjacent downhole assemblies;
- supplying power to the downhole tool from one or both of the adjacent downhole assemblies;
- detecting the power supply or load from each adjacent downhole assembly;
- and
- switching the downhole tool to accept power from both adjacent downhole assemblies, or to accept power from one adjacent downhole assembly and transfer power to the other adjacent downhole assembly.
3 more elements
A downhole tool assembly, comprising;
- first and second electrical power sources intermediate an electrical tool instrument;
- at least one switch intermediate at least one of the electrical sources to selectively allow or disallow power to the electrical tool instrument;
- and
- a microprocessor in electrical communication with the at least one switch.
