摘　　要：漠河-大庆管道途经区域大小河流遍布,一旦管道因冻胀融沉断裂、第三方破坏、水毁等原因发生溢油事故,管内俄罗斯原油(俄油)将可能流入水体造成污染。通过分析俄油自身物性,采用分光光度法和硅胶吸附法测试得到俄油的特征吸收峰和俄油在水体中的质量分数与油膜厚度的关系,得到俄油在水中质量分数与温度的非线性关系,并进行了原因分析。同时测试了俄油在水体中质量分数与温度的关系,通过室内模拟俄油在室温、无风、净水域情况下的扩散,了解水体中俄油的溶解和扩散参数,为生产管理部门制定应急预案和事故处理提供数据支持。Mohe-Daqing Oil Pipeline spans areas with several rivers and streams. Once it is broken due to frost heaving, or damaged by the third party or by flood, the spilled Russian Oil may flow to and thereby pollute the waters. Based on the analysis of Russian Oil＇s physical properties, spectrophotometry and silica gel adsorption methods are used to identify the characteristic absorption peak and the relationship of mass fraction and oil film thickness as well as the non-linear relationship of mass fraction and temperature of Russian Oil in water. Causes thereof are analyzed. Indoor simulation is made on the diffusion of Russian Oil in such conditions as room temperature, no wind and clean waters. As a result, dissolution and diffusion parameters of Russian Oil in water are understood, providing data to the production management department for contingency planning and accident treatment.
