In order to prevent the oil sludge and other solid pollutants produced in borehole operation process of oilfield production from polluting the environment, the impervious cloth is generally used to collect and temporarily store the solid waste. The waste oil-based drilling fluid produced in drilling process is identified by the nation as the hazardous waste, which must be processed, and the thermal desorption is a method with relatively good treatment effect. 5-valve and 8-column system is chosen to analyze thermal desorption non-condensable gas composition in abandoned impervious clothes and oil-based drilling fluid, and chromatography conditions and the valve operation time are selected by tests. According to the operation timetable, a better separation of saturated hydrocarbons, aromatics, olefins, etc in the thermal desorption non-condensable gas can be made; by using the corresponding detector, the qualitative and quantitative analysis of the non-condensable gas components produced by thermal desorption of abandoned impervious clothes and oil-based drilling fluid can be completed by one time. The results show that by using this method, nearly 30 components of the non-condensable gas can be analyzed qualitatively and quantitatively by using one group of samples,which has advantag-es of simple operation and high accuracy.%为了防止油田生产井下作业过程中产生的油泥等固废物污染环境,一般采用防渗布对这些固废物进行收集及暂存,钻井产生的废油基钻井泥浆被国家定为危险废物,必须加以处理,热解析方法是一个处理效果相对较好的方法.选择5阀8柱系统进行废防渗布与废油基钻井液热解析不凝气成分分析,通过实验选择色谱条件,确定阀运行时间,按照该时间运行表,可使热解析不凝气中的饱和烃、芳烃、烯烃等较好地分离;配合相应的检测器可一次性完成废防渗布和废油基钻井液热解析后产生的不凝气成分的定性和定量分析.结果表明,该方法通过一次进样便可对不凝气中近30个组分进行定性和定量分析,具有操作简单、准确度高等优点.
