Abstract: Supported by the Continental Shelf Drilling Program (CSDP), borehole CSDP-2 is not only the first drilling in the central uplift of the South Yellow Sea basin, but also a full-drilling record with a depth of 2 843.18 m. The multi-types and multi-levels oil and gas have been detected in the cores of the Triassic Qinglong Formation, Permian Dalong, Longtan, Gufeng and Qixia Formations,and Silurian Fentou Formation. Three Permian oil sand samples obtained from borehole CSDP-2 indicate a large-scale migration and accumulation of oil and gas in this study area. The geochemical analysis and oil-source rock correlation reveal the near-source hydrocarbon accumulation in the oil sands of 1# and 2#. Among them, the crude oil in the 1# oil sand of the Dalong Formation has obvious genetic relationship with the source rocks of the Dalong Formation and Upper Longtan Formation, the crude oil in the 2# oil sand of the Longtan Formation is closely related to the source rocks of the Lower Longtan, Gufeng, and Qixia Formations; While the crude oil in the 3# oil sand is in obviously low maturity, which may be derived from the Cretaceous and Paleogene source rocks in the depressions on both sides of the central uplift. The mutual corroboration of basin modelling and temperature measurement of hydrocarbon-bearing inclusions shows the multi-stage hydrocarbon accumulation characteristics with relay hydrocarbon generation and wavy hydrocarbon charging between the four sets of source rocks and three sets of reservoirs in borehole CSDP-2, which is benefited from the good sealing of the three sets of caprocks. It proves a relatively broad exploration prospect for marine oil and gas in the South Yellow Sea basin.

Key words: marine hydrocarbon, Meso-Paleozoic, borehole CSDP-2, central uplift, South Yellow Sea basin
