摘要:
      基于盆地结构分析,井-震结合确定沧东—南皮凹陷孔一上亚段残留盆地边界。应用边缘相法和平衡剖面法对孔一上亚段原型盆地边界进行了恢复。综合分析恢复结果表明,沧东—南皮凹陷孔一上亚段地层沉积时期受沧东、徐西断层控制,遭受强烈改造,为后期构造改造的盆地,盆地剥蚀面积大于500 km2,剥蚀率高于20%,且原型盆地与残留盆地的边界亦有较大差异。

Abstract:
      Based on the basin-structure analysis and the combination with the well seismic data, the residual boundary of upper section of first member of Kongdian Formation in Cangdong-Nanpi Depression was recovered. Using marginal facies method and balanced section method, the authors recovered the prototype basin of upper subsection. By analyzing the recovered results, it was concluded that the upper subsection of first member of Kongdian Formation in Cangdong-Nanpi Depression was intensely remoulded and it was a reconstructed basin. The erosion area in the basin was larger than 500 km2 and the denudation rate was higher than 20%, moreover, the boundary of the residual basin differed from that of the prototype basin.
