Abstract

System for å underlette innføring av et verktøy i et brønnhull, spesielt et ikke-vertikalt brønnhull. I én utførelse kan verktøyet fastgjøres i et brønnhull og innbefatter sentrerende, friksjonsreduserende elementer hvis funksjon er å holde verktøylegemet vekk fra brønnhullets vegger. I en annen utførelse innbefatter verktøyet en avstryker som delvis fyller et ringrom som er dannet mellom det sentrerte verktøy og brønnhullsveggene. Den avstrykerflate som vender motbrønnhullets øvre ende, utgjør en fluidfast stempelflate og muliggjør mer effektiv pumping av det sentrerte verktøy ned gjennom brønnhullet.
