DEVELOPMENT AND APPLICATION OF HZ CORROSION INHIBITOR AND SCALE RETARDER

-
Abstract
The production water and scale ingredients were analyzed aim at the problem that since scaling severity affect oil production in j22 and j58 fault. So the causation and types of oil well corrosion and scaling were made clear. Base on it, the HZ corrosion inhibitor and scale retarder was developed though laboratory filter and match. Field testing indicated:the rate of corrosion reached 80%, the rate of scale retarder over 95%.
