琼东南盆地深水区陵水凹陷古近纪同沉积断裂对层序构成样式的控制
Paleogene sydepositional fault and its control on sequence architecture of Lingshui sag, deepwater area of Qiongdongnan Basin, South China Sea
摘要
Abstract
Based on geological and geophysical data, the Paleogene syndepositional fault and its control on sequence archi-tecture of lingshui sag were studied by analyzing the combination features and faulting-activity rate of the fault. The results show that three kinds of frameworks, i. e. , asymmetric graben, symmetric graben and half-graben, were developed individu-ally in the east, middle, and west of lingshui sag. Three kinds of structural paleogeomorphologies, i. e. , up-dip foot slope break belt, down-dip foot slope break belt and gentle slope-break belt, were developed in response to the changes of faulting-activity, which influenced the sequence-infill patterns. Different sequence-infill patterns distributing within tectono-strati-graphic frameworks have characteristic sequence architectures, which will favorably contribute to exploration of potential res-ervoirs and subtle oil pools in deepwater area.关键词
