Abstract

Oppfinnelsen angår en korrosjonsinhibitor som nominelt består av en fenolisk forbindelse og en hydroksid-bærende forbindelse som er istand til å gi en pH på 9 til vann, innarbeidelsen derav i gassinnblandede vannbaserte fluider og skummer, og anvendelsen av disse fluidene i brønnhulls- applikasjoner; særlig applikasjoner utført ved de eleverte temperaturer.The invention relates to a corrosion inhibitor nominally composed of a phenolic compound and a hydroxide-bearing compound capable of providing a pH of 9 to water, the incorporation thereof into gas-mixed water-based fluids and foams, and the use of these fluids in wellbore applications; especially applications carried out at the students temperatures.
