Abstract

Oppfinnelsen vedrører en anordning for spyling av gass- og oljeboringer i underjordisk transportutstyr der borehullene er foret med et hullet foringsrør. Anordningen har en spyledyse med flere innrettede dyser, et dyselegeme som på sin fremre ende har spyledysen og på sin bakre ende har anordnet en spylemiddelledning som kan føres inn i borehullet. Spylemiddelledningen er forbundet med en spylemiddelkilde som står under hydraulisk trykk. På dyselegemets (11) omkrets er det fordelt flere tunger eller lameller (13) som under spylingen spriker utover og reduserer ringtverrsnittet mellom dyselegemet (11) og hhv. borehullets og det hullete foringsrørets vegg.
