惠州凹陷古近系珠海组—恩平组高分辨率层序格架与储层分布规律
|
摘要
利用高分辨率层序地层学理论和技术方法,综合测井、地震和岩芯资料对惠州凹陷深层储层——珠海组和恩平组进行高分辨率层序地层学分析,从中识别出短期、中期、长期3个级别的基准面旋回层序,进一步分析短期旋回层序结构,划分出向上"变深"非对称型、向上变浅非对称型、对称型3种基本结构类型。依据等时地层对比法则并利用地震资料约束进行不同级次基准面旋回层序的联井对比,建立了珠海组和恩平组的等时地层格架,在等时地层格架内进行了单砂体的对比,并在等时地层格架内分析了储层的时空展布规律。
Based on well data and seismic data, the Zhuhai and Enping formations in the Huizhou depression of the Pearl River Mouth basin are divided into short-term, middle-term, and long-term base-level cycles. The structure of the short-term base-level cycles could be subdivided into asymmetric upward-deepening, asymmetric upward-shallowing and symmetric basic structure types. The base-level cycles of different orders are correlated using seismic data and method of cycle isochrostratigraphy correlation. Isochronous stratigraphic frameworks are established and used in the correlation of sand- bodies. Finally, the distribution and evolution of deep reservoirs are analyzed within isochronous stratigraphic frameworks.
