摘要
位于生油岩中的浊积岩砂体吸收围岩生成的油气,在沉积洼陷或它的斜坡地带被完整地保存下来而形成原生油气藏。它不仅被大量钻井资料发现,也被地球化学分析指标所证实。本文以营11、王70等油藏为例,分析浊积岩原生油气藏成油依据和特点,原、次生油气藏的伴生关系及在盆地找油的意义。
As the turbidite sandstone bodies sucked up oil and gas origined from surrounding source rocks and were preserved intactly in the depositional sag or on its slope,can form primacy oil-alas pools.They not only have been discoveried by drilling but also have been confirmed by geochemical criter- ions.Ying-11 and Wang-70 oil pools are taken as examples to analyse crit- erion of the formation and the characteristics of piomary oil-gas pools and to analyse the association between the primary and secondary oil-gas pools, and to indicate the significance for the oil and gas exploration in this basin.
