东道海子地区储层孔隙烃和包裹体烃对比及油源分析
|
摘要
通过分析东道海子地区储层孔隙烃和孔隙烃的生物标志化合物特征来研究区内目标储层烃类来源,分离提取研究区内6口共12个储层分析样中的孔隙烃和包裹体烃,从气相色谱分析(GC)、气相色谱-质谱联用分析(GC-MS)入手,对比孔隙烃和包裹体烃的生物标志化合物特征及区域内3套烃源岩的生物标志化合物分布特征,结果表明:两者的生物标志化合物特征具有显著区别,包裹体烃较孔隙烃内部一致性更好,体现在:正构烷烃的分布上更为完整,Pr/Ph比值更低,甾烷和萜烷的发育程度更高等方面;推测包裹体烃多与二叠系烃源岩有关;孔隙烃多与二叠系和侏罗系烃源岩混源有关。储层烃类的来源分类可为进一步勘探提供一定的地质依据。
The features of the biomarkers of the pore hydrocarbon and inclusion hydrocarbon were comparatively studied in order to determine the hydrocarbon sources of the reservoir in Dongdaohaizi area. The pore hydrocarbon and inclusion hydrocarbon are separated from 12 sandstone samples of 6 wells in the study area,and the features of their biomarkers and the distribution characteristics of the biomarkers of three sets of hydrocarbon source rocks in the study area are compared and analyzed by GC analysis and GC-MS analysis.The results show that,there is significant difference between the biomarkers of pore hydrocarbon and inclusion hydrocarbon: the hydrocarbon in inclusions has better consistency than that in pores,the distribution of its n-alkanes is more complete,its Pr/Ph ratio is lower,and its steranes and terpanes is more mature. It is held that the inclusion hydrocarbon may be related to Permian hydrocarbon source rocks; the pore hydrocarbon may be related to Jurassic and Permian source rocks. The analysis of reservoir hydrocarbon sources can provide certain geological basis for the further exploration of the study area.
