摘要
甾萜烷生标分析表明,BZ28-1油田存在两种类型的原油,一类原油主要来源于渤中凹陷东营组下段烃源岩,而另一类原油主要来源于黄河口凹陷沙河街组烃源岩.原油物性和补身烷系列化合物分析表明,BZ28-1油田凝析油来源于渤中凹陷.天然气组分和碳同位素研究表明,BZ28-1油田天然气为渤中凹陷和黄河口凹陷混合来源,以渤中凹陷高-过成熟气为主.
Biomarkers show that there are two types of oil in BZ28-1 field,one generated from the Lower Dongying source rock in Bozhong depression,the other from the Shahejie source rock in Huanghekou depression. Based on analyses of oil property and drimanes, the condensate in BZ28-1 can be believed to come mainly from Bozhong depression. For natural gas in the field,a study of composition and carbon isotope indicates that there is a mixed source from Bozhong and Huanghekou depressions,with high-over mature gas from Bozhong depression predominant.
