摘要
宗巴音油田位于蒙古东戈壁盆地宗巴音凹陷内,盆地勘探程度很低,具有很大的油气勘探潜力。通过对油田内地震、测井、取心等地质资料的整理和研究,应用层序地层学方法确定了本区的区域构造演化特征、层序地层格架和沉积相展布特征。弄清油区的地层格架和沉积相展布特征,是油田挖潜和区域勘探开发的实际需要,对于确定油田下一步的勘探方向和开发思路具有十分重要的意义。由于油田资料较凹陷内的其他区域相对丰富,因此本区层序地层和沉积相展布的研究对凹陷其它构造部位的勘探开发也是非常有利的。
Zongbayin oilfield is located in Zongbanyin sag of East Gobi Basin,Mongolia.There is a low exploration degree as a result of a large exploration potential.In this study,the geological data of seismic,well-logging and coring in the oilfield is analyzed;and the regional structure evolution,sequence stratigraphic framework and sedimentary facies distribution are determined by sequence stratigraphy.To understand both stratigraphic framework and sedimentary facies distribution not only can meet the demand from oilfield potential tapping and regional E & P,but also is significant to determine further exploration direction and development thought.Since oilfield's data is more abundant than that in other areas of sag,the research on stratigraphic sequence and sedimentary facies distribution is helpful for an E & P of other structures in the sag.
