Chemical actuation of downhole tools |
摘要 |
Downhole tools and systems can be actuated chemically by placing a chemical sensor downhole and introducing a chemical slug into fluids being pumped downhole. When the slug reaches the sensor a reaction in the sensor may be employed to trigger an event (e.g., actuation) or may cause a count to increase by one on its way to a full count and actuation of a tool or system downhole.
