辽河三角洲土壤中石油类含量光谱分析初探

Spectral Analysis on Hydrocarbon Concentration in Soil of Liaohe River Delta

石油类物质对土壤的污染在油田区域内是一个普遍存在的问题。全面了解土壤中石油类物质含量是评价土壤石油污染的前提条件。对土壤石油污染评价的传统方法是在野外实地进行大量土壤采样,然后在试验室内分析石油类物质的含量。文中提出了利用少量野外土壤石油类物质样品,并结合野外光谱测量的方法对土壤中石油类物质进行分析的新方法。该方法应用于辽河三角洲,具有快速、省钱、省时、省力的特点,能对土壤中石油类物质含量进行宏观分析。满足了油田开发对土壤及环境污染评价的需要,并能为制定油田开发管理保护对策提供辅助信息。

Soil around oilfields may be always polluted by oily matters. The measurement of hydrocarbon concentration in soil is the key for evaluating soil pollution in oilfield. The traditional analysis method is to collect a lot of soil samples in the field at first, then to measure the hydrocarbon concentration in soil in laboratory, and finally evaluate the soil pollution degree. This method needs lots of time and cost. A new method by integrative measurement of a little soil samples and field spectra analysis was put forward. This method has been successfully used to forecast hydrocarbon concentration in soil and evaluate soil pollution in Liaohe River Delta. The analysis result is consistent with that of field survey and the known researched result.
