为了分析油田采出水及原油淋滤液挥发性组分的特性,采用气相色谱质谱法测试了油田采出水及脱水原油淋滤液中的挥发性有机物(VOCs),并通过土柱试验考察了原油可溶组分通过不同土壤厚度后的浓度变化规律。结果表明:在油田采出水中测得92种可溶性VOCs,在脱水原油淋滤液中测得29种可溶性VOCs,经过10 cm厚度的土壤后溶解组分大部分被吸附。苯系物和萘是原油的主要溶解组分,可以作为油田地下水污染的主要研究对象,土壤对原油淋滤液中VOCs组分具有较强的吸附能力。
In order to analyze the characteristics of the volatile components in the leachate from the produced water and the crude oil, the volatile organic compounds (VOCs) in the leachate from the produced water and the dehydrated crude oil were tested by gas chromatography-mass spectrometry, and the crude oil was tested by soil column The variation of the concentration of components after different soil thicknesses. The results showed that 92 kinds of soluble VOCs were detected in the produced water and 29 kinds of soluble VOCs were detected in the dehydrated crude leachate. Most of the dissolved components were adsorbed after 10 cm thick soil. BTEX and naphthalene are the main dissolved components of crude oil, which can be used as the main research object of groundwater pollution in oilfields. Soil has strong adsorption capacity for VOCs in the leachate of crude oil.
