【摘要】 根据谭庄-沈丘凹陷的地震剖面、钻井资料和区域地质资料,分析了下白垩统断裂的发育和活动特征。按照走向可划分为3组,NWW-NW向、NNE-EW向及近SN向断裂系统。叶鲁断裂和商水断裂分别是谭庄-沈丘凹陷南、北边界的主控断裂,控制着凹陷内下白垩统和新生界的沉积与保存。主要有4期断裂活动:晚侏罗世-早白垩世巴村期-永丰早期断裂活动期;早白垩世末期断裂活动期;新近纪断裂活动期;古近纪断裂活动期。更多还原

【Abstract】 Based on seismic profile,drilling data and regional geologieal data,the fault feature of early Cretaceous Faults in Tanzhuang-Shenqiu Sag is analyzed.According to directions of fault,can be divided into NWW-NW,NNE-EW and close to the SN.YeLu fracture and ShangShui fracture were basin-bounding master fault of TanZhuang-ShenQiu Sag.,controls within the early cretaceous and Cenozoic sedimentary and preservation.There are four main fault activity: late Jurassic period of early creatceous;The end of early cretaceous,Neogene,Paleogene.更多还原
