高分辨率层序地层特征及其对储层发育的影响——以胡状集油田胡5块沙三段上、中亚段为例
High Resolution Sequence Stratigraphy and Its Effect on Reservoir——Taking the Stratigraphy in the Upper and Middle Positions of Es3 Member of Block Hu 5 in Huzhuangji Oilfield as an Example
【摘要】 为了满足开发区寻找剩余油分布的需要 ,以高分辨率层序地层学为指导 ,运用地层基准面原理 ,通过岩心、测井、地震资料的综合解释 ,在濮阳凹陷胡状集油田胡 5块沙三段上、中亚段中识别出短期、中期和长期 3种规模的地层旋回 ,分别响应于不同级次的基准面旋回。对沙三段上亚段 3~ 4及中亚段 1~ 10砂组进行对比 ,建立了全区高分辨率层序地层格架 ,并就层序对储层分布的控制及层序内主要沉积微相的展布进行了分析。
【Abstract】 To find the remaining oil in the development area,the high resolution sequence stratigraphic analysis is made for the upper and middle submembers of Es 3 in Block Hu 5 of Huzhangji Oilfield in Puyang depression,three sizes of stratigraphic cycles (short term, mid term and long term)are identified The stratigraphic cycles correspond respectively to the base levels of different orders Through stratigraphic correlation of No 3~4 sandsets in upper submember and No 1~10 sand sets in middle submember of Es 3 in the whole area, a high resolution sequence stratigraphic framework of the whole area is established, the control of the sequence on the reservoir distribution and the arrangement of main sedimentary facies within the sequence are analyzed
