Corrosion of pipe and equipment is aggravated owing to the deposition of elemental sulfur. To explore elemental sulfur hy-drolysis corrosion mechanism,pH value and S2-and SO2-4 concentration of elemental sulfur hydrolysis solution were measured,the in-fluences of temperature, reaction times and elemental sulfur content on sulfur hydrolysis reaction were researched. The results showed that testing temperature played a crucial role in sulfur hydrolysis,only did temperature exceed a critical value(60℃),hy-drolysis reaction occurred. There was an induction period(2h)in the process of elemental sulfur hydrolysis,thereafter,hydrolysis de-gree increased with the increasing of reaction time. And sulfur content also affected sulfur hydrolysis. In addition,a model of elemen-tal sulfur hydrolysis was built based on the experiment results,and hydrolysis mechanism was discussed,“hydrogen ion carrier”could self-catalyze the hydrolysis of elemental sulfur.%元素硫沉积加剧油气田管材和设备的腐蚀，为探寻元素硫水解腐蚀机理，对元素硫水解后溶液的pH值及S2-、SO2-4含量进行了测定，研究实验温度、反应时间及硫含量对硫水解反应的影响。结果表明：实验温度对硫的水解起决定作用，只有当温度超过某一临界值(60℃)，水解反应才能发生；硫的水解存在诱导期(2h)，其后，硫的水解反应程度随反应时间的延长而增强；硫含量同样能够影响硫的水解。基于实验结果，建立了元素硫水解模型，讨论了元素硫水解机理，水解过程中所形成的“氢离子载体”能自催化元素硫的水解。
