油气的生成、运移、储存过程与地下水有着密切的关系。有机酸、酚、溶解气、苯系物等是有机质向烃类转化过程的产物,并可能溶解于孔隙水中。因此油田水或油藏附近地下水中有机酸、酚、溶解气、苯系物的含量一般随接近含油边界或主要生油和储集层而升高,在查清区域地质条件的基础上,综合岩石有机地化指标,可预测油气藏。 本文综述了国内外石油化学勘探油气藏的几种方法,并以大量的分析资料为基础研究了松辽盆地北部部分地区,不同层位的油田水与非油田水中有机酸、酚、溶解气含量的变化特征,探讨了地层水中“指纹标志”化合物的含量与油气藏的关系。
Hydrocarbon generation, migration, storage and groundwater has a close relationship. Organic acids, phenols, dissolved gases, benzene compounds, etc. are the products of the conversion of organic matter to hydrocarbons and may dissolve in pore water. Therefore, the contents of organic acids, phenols, dissolved gases and benzene compounds in the groundwater near the water or oil reservoir generally increase with the approaching of the oil boundary or the main oil and reservoir. Based on the investigation of the regional geological conditions, Indicators of organic geochemistry of rocks can predict reservoirs. In this paper, several methods for petrochemical exploration of oil and gas reservoirs at home and abroad are reviewed. Based on a large amount of analytical data, the contents of organic acids, phenols and dissolved gases in water and non-oil fields of some layers in the northern Songliao Basin are studied. The relationship between the content of “fingerprint” compounds and reservoir in the formation water is discussed.
