摘要
从钻井、测井层序地层学研究入手 ,以三维地震勘探资料为基础 ,研究黄骅坳陷北部新港地区尚未开发的潜在有利油气储集层系———沙三段的层序地层特征 .三维地震层序地层学分析将沙三段分为上中下 3个层序 ,3个层序内均有较厚的低位扇发育 ,上覆高位体系域可形成良好盖层 ,内部储盖组合发育十分完好的沙三段 ,可以形成较好的油气富集 .
Shasan Member is a very important and potential reservoir in the Xingang region, north of Huanghua depression. This paper describes, in line with the three_dimensional seismic exploration data deriving from the drilling, well_logging and sequence stratigraphic references, sequence stratigraphic features in Shasan Member, Xingang region. The Shasan Member is divided into three sequences: upper, middle and lower sequences, in which occur relatively thick low_stand fans. The upper high_stand system tract may serve as an excellent cap rock. In summary, perfect reservoir_cap association occurs in the Shasan Member, favorable for the formation of the relatively good hydrocarbon concentration.
