中国古生代海相油气资源潜力巨大

自1984年塔里木盆地沙参2井实现我国古生代海相油气首次重大突破以来，中国不但甩掉了古生代海相无油的帽子，而且相继在塔里木、鄂尔多斯、四川、准噶尔等盆地发现几十个油气田，建立了中国古生代海相成油理论和相应的油气勘探技术系列。通过全国古生界油气资源前景研究，在东北、南华北、柴达木-河西走廊、青藏等地区发现未变质的古生界烃源岩，进一步证明我国古生界油气资源潜力巨大。

Great hydrocarbon potential in the Paleozoic m arine sequences in China

In1984，China made a breakthrough in petroleum exploration in the Paleozoic marine sequenceswith the discovery of the Shacan-2well in Tarim Basin.Since then China has not only leftbehind thewrong idea that there is no hydrocarbon in the Paleozoic marine sequences in China，but also found tens of oil and gas fields in Tarim Basin，Sichuan Basin，Ordos Basin and JunggarBasin.Theories on hydrocarbon generation and accumulation in the Paleozoic marine sequences in China have been brought forward and corresponding exploration techniques have been developed.According to the study of resource potential in the Paleozoic in China，the Paleozoic source rocks，which have not experienced metamorphism，occur in NortheastChina，southern North China，Qaidam Basin，the Hexi corridor and the Qinghai-Tibet area，further proving the great hydrocarbon potential in the Paleozoic marine sequences in China.
