Study of Mud Inhibitor HZ-1

Inhibitor HZ 1 was synthesized by the reaction of amine and alkylogen. It has a well corr-osion inhibiting efficiency in salt water or mud. The effects of solvent, reactant ratio, temperature and pH value on its synthesis and corrosion inhibiting efficiency are studied, and of these factors, reactant ratio has greatest effect. The optimum synthetic condition and reasonable group structure of HZ 1 inhibitor are determined by experiments. The inhibitor has little effect on the rheological property of mud. It over comes the shortcomings of amine inhibitors that make the viscosity and water loss of mud increase and make the rheological property of it bad. The experiments only illustrate the corrosion inhibiting efficiency of the inhibitor when there are not other additives. The corrosion inhibiting rate of it is 0.06 mm/a when its mass content in mud is 0.04%.
