摘要
在对牛心坨地区油藏地质特征精细研究基础上,从油气生成、运移、生储盖组合等油气成藏控制因素入手,对区内成藏规律进行了综合分析,认为牛心坨地区早期断裂控制洼陷的形成及储层的沉积,晚期断裂控制油气运移和聚集,中央构造带为油气聚集的主要场所,牛心坨油层为主要含油层系,近距离运移及生、运、储相处一体是油气富集的主要控制因素。在此基础上对牛心坨周边所有圈闭进行综合评价,发现有利圈闭3个,具有钻探部署潜力。
This paper studies reservoir geology and analyzes hydrocarbon accumulation conditions in respects of generation,migration, source-reservoir-caprock association in Niuxintuo area.It is understood that in this area the early faulting controlled sag formation and reservoir sedimentation,the late faulting controlled hydrocarbon migration and accumulation,and the central structural belt is the main spot of hydrocarbon accumulation.Niuxintuo reservoir is the major oil-bearing series,where short distance migration and integrated generation-migration-reservoir condition dominated hydrocarbon accumulation.All traps around Niuxintuo have been evaluated and 3 favorable traps are considered to have exploratory drilling potential.
