| 摘 要： | 井震结合对川西白马庙气田蓬莱镇组进行了多级次高分辨率层序地层对比。首先对不同级次层序界面进行识别，然后依据相序、岩石的物理性质、地层的接触关系等特征并结合地震层序界面追踪，进行单井不同级次基准面旋回层序识别划分，划分出短期、中期和长期三个级次的基准面旋回。选取密集井网的联井剖面，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，建立高精度的等时地层对比格架，在等时地层格架内进行了单砂体的对比。最后在等时地层格架内分析了储层的时空展布。

| Abstract: | On the basis of integrating well data and seismic data,sequence boundaries of different orders are recognized.Base-level cycles of three orders(short scale,middle scale and long scale)of every single well are recognized according to facies succession,physical character of rock,contacted manner of strata and seismic interpretations.Within dense grid well-connecting profiles,base-level cycles of different order are correlated in the restriction of seismic interpretations.Isochronous stratigraphic frameworks are established and single sand-body is correlated within them.Finally,the distribution and evolution of reservoir are analyzed within isochronous stratigraphic frameworks. |
