摘要
重点以轻烃和生物标志物综合研究了松辽盆地北部古龙地区葡萄花油层凝析油气、轻质油气的来源与成因。结果表明该区油气（葡萄花油层）主要与齐家———古龙凹陷青山口组高熟腐泥型烃源岩有关，而一些轻质油气还存在姚家组泥岩局部成烃的贡献。最后论述了该区葡萄花油层凝析气藏的形成与分布规律。
A synthetic study was carried out on the sources and genesis of gas condensate, light oil and gas in the Putaohua Formation in Gulong area of northern Songliao Basin, using principally light hydrocarbons and biomarkers. The results indicate that the oil and gas in the Putaohua Formation in this area are mainly related to highly-mature sapropelic source rocks of Oinshankou Group in Qijia-Gulong Depression, with some of the light oil and gas from the local contribution of Yaojia Group mudrocks. The formation and distribution of gas condensate reservoirs in the Putaohua Formation are also discussed.
