Abstract

Foreliggende oppfinnelse er en fremgangsmåte og anordning for selektiv aktivering og avaktivering av et antall hydraulisk drevne nedihullverktøy (12, 14) med et system som inneholder en enkelt elektrisk ledning (30) og en enkelt hydraulisk ledning (28) som er koplet i parallell med individuelle kontrollere (20, 22) tilknyttet hvert nedihullverktøy.The present invention is a method and apparatus for selectively activating and deactivating a plurality of hydraulically driven downhole tools (12, 14) with a system containing a single electrical line (30) and a single hydraulic line (28) coupled in parallel to individual controllers (20, 22) associated with each downhole tool.
