南黄海盆地北部坳陷正反转构造

STUDY OF POSITIVE INVERSION STRUCTURES IN THE NORTH DEPRESSION OF THE SOUTH YELLOW SEA BASIN

  • 摘要: 南黄海盆地北部坳陷的东北凹、北凹、中凹、南凹等凹陷发育有多种类型的正反转构造,包括穿透断展型、挤压褶皱型、逆断层型等。主要反转期为渐新世和上新世末,其中渐新世的构造反转影响较大。太平洋-欧亚板块汇聚速率变化是控制南黄海盆地北部坳陷新生代反转构造发育的重要因素。正反转构造有利于油气藏的形成,但反转强度较大时可能使油气藏的保存条件变差。

     

    Abstract: Several types of positive inversion structures are developed in the Cenozoic strata of the Northeast Sag, North Sag, Middle Sag and South Sag in the North Depression of the South Yellow Sea Basin, including penetrated fault-propagation type, compressive fold type, reversed fault type, and so on. Oligocene and the end of Pliocene are the two main inversion periods, and the structural inversion in Oligocene is more obvious. The convergence rate between the Pacific Plate and Eurasia Plate is an important factor controlling the development of inversion structures in Cenozoic in the North Depression of the South Yellow Sea Basin. The positive inversion structures are favorable to hydrocarbon accumulation and unfavorable to hydrocarbon preservation if the intensity of tectonic inversion is great.
