摘要: 南华北盆地周口坳陷周参10井低产油流的发现,无疑为周口坳陷油气勘探突破带来了希望。借助原油及岩石轻烃指纹气相色谱分析方法进行直接油/源对比,研究结果证实该低产油流为混源,主力油源来自下白垩统暗色泥岩和中下侏罗统煤、暗色泥岩及碳质泥岩,其中轻质组分主要由中下侏罗统源岩贡献,并就其成藏条件进行了全面综合分析。

Abstract: Discovery of underproductive oil flow in the Well ZC 10 of Zhoukou depression in the Southern North China basin has brought hope for hydrocarbon exploration success.Direct hydrocarbon/source comparison is conducted with lighter hydrocarbon fingerprint,proving that,this oil flow is of mixed source,primarily the Lower Cretaceous dark mudstone and the Middle and Lower Jurassic coal,dark mudstone and carbargillite.Lighter hydrocarbon comes from the Middle and Lower Jurassic.Accumulation condition is analyzed.
