POWER SUPPLY FOR DOWNHOLE INSTRUMENTS

摘要

In one embodiment, a power supply that is adapted for supplying power to a downhole tool is disclosed. The power supply includes an energy source coupled to a control circuit and a rechargeable energy storage that is configured to operate at a temperature within a temperature range between about 80 degrees Celsius to about 210 degrees Celsius. The source may include at least one of a battery, a connection to an external supply of electrical energy and a generator that is configured for translating energy experienced by the downhole tool into the electrical energy. The control circuit may be configured for receiving electrical energy from the source and storing the electrical energy in the energy storage.
