大庆油田石油污染土壤原位降解组分演变特征分析OACHSSCD
Analysis of In-situ Degradation Component Evolution Characteristics of Petroleum-Contaminated Soil in Daqing Oilfield
石油是现代工业体系的核心能源,勘探、开采、炼化及储运过程中会产生泄漏与排放,污染土壤环境.为探究原位降解组分演变特征,采用气相色谱法对大庆油田污染土壤进行为期 2 年的原位追踪试验.结果表明,石油烃降解遵循"低碳及正构烷烃优先"的动力学特征.色谱主峰碳向高碳数(碳链 C25～C29)漂移被证实为评价降解深度的可靠指标.研究成果为油田土壤治理提供了科学依据.
Petroleum is the core energy source of modern industrial systems,and there are leaks and emissions during exploration,extraction,refining,and storage processes,which pollute the soil environment.In order to investigate the evolution characteristics of in-situ degradation components,a 2-year in-situ tracking experiment is conducted on polluted soil in Daqing oilfield by using gas chromatography.The results indicate that the degradation of petroleum hydrocarbons follows the kinetic characteristics of"low-carbon and n-alkanes priority".The drift of chromatographic main peak carbon towards high carbon numbers(carbon chain C25～C29)is confirmed as a reliable indicator for evaluating degradation depth.The research results provide scientific basis for soil remediation in oilfields.
