  • Well CSDP-2 is the first overall coring well implemented by the Continental Shelf Drilling Program (CSDP) in the Central Uplift of the South Yellow Sea Basin, eastern China, whose completion depth is 2 843.18 m and mean drill-core rate is up to 97.7%.

Abstract: Well CSDP-2 is the first overall coring well implemented by the Continental Shelf Drilling Program (CSDP) in the Central Uplift of the South Yellow Sea Basin, eastern China, whose completion depth is 2 843.18 m and mean drill-core rate is up to 97.7%. Based on the property of cored rocks, logging data, rock thin sections and other test data of Well CSDP-2, it is accurately distinguished in this paper that the rock types, sedimentary structures and lithological association sequences of Upper Paleozoic rocks in the Central Uplift of the South Yellow Sea Basin and then discuss their related sedimentary environments and vertical variations. The Devonian-Carboniferous-Permian strata drilled by Well CSDP-2 contain not only clastic rocks but also carbonate rocks and develop many sedimentary facies including delta, shore, tidal flat, carbonate platform and shallow shelf. In addition, the South Yellow Sea Basin has been experienced 2 completed transgressive-regressive cycles. Controlled by this mechanism, this region developed a clastic depositional system of sea-tidal flat, a carbonate depositional system of tidal flat-lagoon-grain beach, and a delta depositional system from bottom to top, indicating a sedimentary filling process from marine facies to transitional facies.
