【摘要】：利用岩心及测井资料,建立辽河油田曙一区杜84块SAGD开发区馆陶组高分辨率层序地层格架,分析基准面旋回变化与储层隔夹层分布的关系。结果表明:杜84块馆陶组可识别出5期中期基准面旋回和1期长期基准面旋回,地层以发育物性隔夹层为主;中、长期基准面旋回的变化是储层内部隔夹层分布的重要控制因素,以中期基准面旋回为基本单元,中期基准面旋回的变化控制其内部隔夹层纵向分布规律,长期基准面旋回的变化控制中期基准面旋回内部物性隔夹层类型的多样性;形成于中期基准面旋回变化不同阶段的物性隔层或物性夹层界面之上易形成多种类型的剩余油富集。该结果为冲积扇储层的隔夹层分布研究提供参考。
[Abstract]:Based on core and logging data, a high-resolution sequence stratigraphic framework of Guantao formation in block du 84 of SAGD development zone in Shu1 area of Liaohe Oilfield is established. The relationship between base-level cycle change and reservoir intercalation distribution is analyzed. The results show that Guantao formation in block Du84 can identify the intermediate base-level cycle and the long-term base-level cycle in the first stage. The variation of the long-term base-level cycle is an important controlling factor for the intercalation distribution in the reservoir. Taking the medium-term base-level cycle as the basic unit, the variation of the medium-term base-level cycle controls the longitudinal distribution law of the intercalated intercalation inside the reservoir. The variation of the long-term datum cycle controls the diversity of the intercalation types of physical properties within the intermediate datum cycle. Various types of residual oil enrichment are easily formed on the physical barrier or the interface of the physical intercalation which is formed at different stages of the intermediate base-level cycle change. This result provides a reference for the study of the intercalation distribution of alluvial fan reservoir.
