DOWNHOLE POWER GENERATOR |
摘要 |
A downhole tool includes a housing. A magnet, an inductor, and a piston are positioned within the housing. The piston moves from a first position to a second position in response to a pressure of a fluid in the housing increasing. A distance between the magnet and the inductor varies when the piston moves, thereby causing the inductor to generate power. |
