Downhole Supercapacitor Device

摘要

Certain aspects and features of the present invention are directed to a supercapacitor device that can be disposed in a wellbore through a fluid-producing formation. The supercapacitor device can include a body that can be disposed in the wellbore, a supercapacitor disposed in the body, at least two terminals disposed at least partially outside the body, and an actuation mechanism. The supercapacitor stores energy. The terminals can be electrically connected with the supercapacitor. An electrical connection between the supercapacitor and the terminals can cause the energy to be discharged from the supercapacitor in response to a conductive material providing an electrical path between the at least two terminals. The actuation mechanism can selectively prevent a deployment of the supercapacitor device in the wellbore from causing a discharge of the energy from the supercapacitor.

主权项

1. A supercapacitor device configured to be disposed in a wellbore through a fluid-producing formation, the supercapacitor device comprising:
a body configured to be disposed in the wellbore; a supercapacitor disposed in the body and configured to store energy; at least two terminals disposed at least partially outside the body, the at least two terminals configured to be electrically connected with the supercapacitor, wherein an electrical connection between the supercapacitor and the at least two terminals is adapted to cause the energy to be discharged from the supercapacitor in response to a conductive material providing an electrical path between the at least two terminals; and an actuation mechanism configured to selectively prevent discharge of the energy from the supercapacitor when the supercapacitor device is deployed into the wellbore.
