摘要
依据岩心和测井资料,对泌阳凹陷新庄辫状三角洲沉积体系进行了沉积微相划分和微相特征分析。在此基础上,进行了沉积模式和油气储集性能的研究。研究认为,水下分流河道、河口砂坝是该区最好的油气储集体,其它微相依次为辫状河道、浊积岩、前缘席状砂和决口扇。研究结果可为下一步的滚动勘探提供地质依据。
Characteristics of braided delta microfacies and depositional systems in Biyang depression are analyzed through comprehensive analysis of drill cores and logging data.Sedimentary mode and reservoir property are studied on the above basis.It is believed that submerged branch channel and distributary mouth bar are better oil and gas reservoirs in this area,and braided channel,turbidite sandstone,sand sheet and splay sandstone are next.The result of the study provides geologic basis for exploration and development.
