PALEOZOIC DEEP STRUCTURE AND MARINE PETROLEUM EXPLORATION IN THE NORTHERN JIANGSU BASIN

Due to stages of tectonic movements,deep sediments of Paleozoic in the Northern Jiangsu Basin have been completely transformed.Based on field geologic survey and underground geophysical data,geologic-geophysical comprehensive interpretations have been done.Paleozoic deep in the basin can be divided into 2 layers presently and is not totally inheritant.Combined with destroyed ancient accumulations regionally,it is suggested that tectonic ways should be used in marine petroleum explorations in the region.
