Abstract

Oppfinnelsen vedrører en enhet for nedihullsbrønnverktøy innbefattende en verktøyenhet med minst en første flu id led n ing og en fluidreturledning. Verktøyenheten danner et brønnringrom i brønnhullet. Verktøyenheten er tilveiebragt med minst ett stempel for deling av brønnringrommet i minst to brønnringrom. Fluidkommunikasjonen mellom næerliggende brønnringrom på hver side av stempelet styres med den relative bevegelsen mellom den første fluidledningen og et styreelement.
