Abstract: After entering the period of high water cut exploitation in oil field, the corrosion and scale of equipments for oil production is becoming more and more severe, which has been causing a great economic loss of oil field exploitation. Because of the defect ex-fisting in the method of adding the liquid corrosion-scale inhibi-for into wells, we have brought forward a new method of using
solid darrosion-scale inhibitor for inhibiting contusion and scale. In this paper, we introduce a way of producing solid corrosion-scale inhibitor based on the analysis of the cause of corrosion and scale: The inhibitor has presented a very excellent efficiency when applied on the spot.

Key words: corrosion, scaling, solid corrosion-scale in-hibitor, high water content
