【摘要】 通过胜利油区某探区烃类组份的相关性特征、三维荧光特征、甲烷碳同位素特征及烃类组份的某些比值特征等 4项参数的对比分析 ,认为该区土壤吸附烃组份异常的成因主要属热解成因的油田伴生气或凝析气 ,基本可排除地表生物降解成因气、人工污染气、煤成气形成异常的可能性。土壤吸附烃组份异常推断为深部油气藏在地表的响应更多还原

【Abstract】 It is considered that soil absorbed hydrocarbon anomalies in a area of shenli oil field is caused by associated gas and condensing gas of heat solution oil field by comparison analysis of 4 coefficients including hydrocarbon correlation character, three dimensional fluorescence character, methan’s Carbon Isotope character and some ratio characters of hydrocarbon composition. The study wxcluded the possibility that the anomaly would be caused by surface biological degradation, human contamination or coal caused gas. The absorbed hydrocarbon in soil is supposed to be the correspondence on the surface of deep rooted oil and gas pool.更多还原
