中国古生界油气勘探前景展望

PROSPECTS OF PETROLEUM EXPLORATION IN THE PALEOZOIC OF CHINA

几十年来,中国古生代海相成油一直是国内外石油地质学家关注的大问题,1984年塔里木盆地沙参2井实现古生代海相油气重大突破,首次证明“中国古生界海相含丰富的石油”。但中国古生界海相油气前景如何?其一认为是油气勘探重点战略接替领域,其二认为前景不大,只是天然气勘探的辅助领域之一。本文从近10年来古生界油气勘探重大进展、古生界油气资源潜力、有利的地质构造条件、多时代成油组合、广泛的勘探领域等方面论述了中国古生界海相油气勘探前景巨大,将是中国油气勘探重要的战略接替领域之一。

In the past several decades, the marine origin of Paleozoic oil and gas in China has long been an important problem to which petroleum geologists pay great attention. A major breakthrough was made in 1984 when well Shacan 2 encountered Paleozoic oil of marine origin in the Tarim basin, which for the first time demonstrates that ＂the Paleozoic marine deposits in China contain abundant oil＂. However,how are the prospects of Paleozoic marine oil and gas in China？ Some people think that they are a key strategic substitute area for petroleum exploration, while others consider that they have no broad prospects but are only an auxiliary area for petroleum prospects. From the great advances in Paleozoic petroleum exploration in the past decade, Paleozoic petroleum potentials, favorable tectonic conditions, association of multi-epochal petroleum and wide exploration areas, the author proposes that Paleozoic marine oil and gas in China has great exploration prospects and will be one of the important strategic substitute areas of petroleum exploration in China.
