摘要
Abstract
The performance of the ferric ion complex sulphide scavenger is tested in laboratory. This sulphide scavenger is synthesized by ferrous and derivate of carbohydrates. It is easy dissolved in water-base drilling fluid and cannot subside when the pH value is 12, while the desulphuration efficiency can get as high as 98.6% as the pH value of drilling fluids is 9. Under 70℃, the highest corrosion control efficiency value is 71.23 %, which can remarkably slow down the corrosion rate for drilling rig. The sulphide scavenger is good compatible with poly-sulfonate drilling fluids, and won't obviously affect the rheology and filtration loss of the drilling fluid. The desulfuration has rapid reaction velocity and high reaction effectiveness. It not only prolong the life of drilling rig, but also protect people not be infected by H_2S.关键词
