Abstract

Det er beskrevet et ned-i-hulls verktøy som fungerer som en underrømmer eller, alternativt, som en stabilisator i et underrømmet borehull. Én utførelsesform av verktøyet omfatter én eller flere bevegelige armer posisjonert inne i et legeme som omfatter en strømningsboring derigjennom i fluidkommunikasjon med ringrommet i brønnboringen. Verktøyet alternerer mellom kollapset og ekspandert stilling i respons til forskjeller i fluidtrykk mellom strømningsboringen og ringrommet i brønnboringen. I én utførelsesform beveges verktøyet automatisk i respons til trykkforskjeller. I en andre utførelsesform må verktøyet selektivt aktiveres før det kan beveges. Når verktøyet ekspanderes, forflyttes armene fortrinnsvis aksielt oppover, samtidig som de bringes radielt utover fra legemet.Verktøyets ekspanderte diameter kan justeres ved overflaten uten å endre eller skifte komponenter. Armene kan omfatte blokker som danner inngrep med borehull og som omfatter kuttestrukturer eller slitestrukturer, eller begge deler, avhengig verktøyets funksjon.
