Tertiary geology and minerals prospecting Institute of Shandong Province issued a news release saying, the hospital assumed the construction " East China Sea Continental scientific drilling project "CSDP—2 Well before the completion of one hole deep 2843.18 Meters, set a world Marine Geosciences drilled core hole depth record.
It is reported that the continental scientific drilling project led by the China geological survey Bureau, Qingdao Institute of marine geology responsible for implementation. Project area is located in the abandoned Huanghe River estuary South Yellow Sea waters, offshore East of Lianyungang 83 sea depths near 30 meters. 2015 years 3 months 29 days Spud,2016 years 9 months 13 Completed over 530 More than ten days. Construction process was demonstrated for the first time in South of Mesozoic - Paleozoic marine strata in the presence of oil and gas resources.
Supporting construction " Sea, first " Offshore drilling platforms, third geological exploration Institute developed the production of Shandong province, at a depth of 30 Meter in shallow shelf areas, wind 14 Level, costs only a similar oil drilling platform 1/10 。
Continental shelf is one of the global sea-land interaction is the most active, as a bridge connecting the land and the sea, has been the focus of international geoscience field area. CSDP-2 wells in South Yellow Sea coring drilling the first well in the Central uplift, a South Mesozoic - Paleozoic sequence stratigraphic framework of the standard, restoration of the South yellow sea sediments and structural environment, revealing the southern Yellow Sea oil and gas geological engineering is of great significance.
