以黄骅坳陷港西开发区明化镇曲流河储集层为例,探讨了河道砂体内部构型分析方法。研究了曲流河道砂体内点坝分布模式及规模、废弃河道及点坝的识别标志,以及点坝内部构型定量分布模式。进一步研究了侧积层倾向、倾角及侧积体宽度,并在单井泥质侧积层解释的基础上,以点坝内部构型为指导,结合动态分析,对泥质侧积层的井间分布进行了预测。
Taking the meandering stream reservoir in Minghua Town, Hong Kong West Development Zone, Huanghua Depression as an example, the method of analyzing the internal structure of channel sandbody is discussed. The distribution pattern and size of point dams in meandering channel sand bodies, identification marks of abandoned river channels and point dams, and quantitative distribution patterns of internal configuration of point dams were studied. Based on the interpretation of single-well muddy side strata and the internal configuration of point dam, combined with the dynamic analysis, Between the distribution was predicted.
