Abstract
Det er beskrevet et hydraulisk system for et elek- tronisk kontrollert brønntestingsverktøy. Verktøyet (100) drives med et trykkdlfferenslal mellom brønn- rommet og et trykkavlastningskammer med hovedsakllg atmosfærisk trykk, definert i verktøyet. Kraftkanaler (124) kommuniserer et stempel (112) med brønnrommet og avlastningskammeret (108). Normalt lukkede elektriske solenoide kontrollventiler (126A, 126B og 126C) er anordnet direkte i kraftkanalene (124) for å kontrol- lere fluldumstrømmen gjennom disse. En trykkregulator (146) regulerer trykkdlfferensialet over de elektriske solenoide kontrollventilene (126A, 126B, 126C og 126D).
