High performance phosphorus-containing corrosion inhibitors for inhibiting corrosion by drilling system fluids |
摘要 |
<p>A corrosion inhibitor comprising a quantity of a phosphorylated oxyalkylated polyol at a pH of 5.0 or higher which produces a first level of corrosion loss in an oxygenated corrosive system under given conditions, and an amount of a passivating agent effective to decrease the corrosion loss under said given conditions to a second level which is less than the first level. The passivating agent minimizes the impact of the corrosion inhibitor on the rheology of drilling system fluids.</p> |
