从近期发现的油气新领域展望中国油气勘探发展前景

近年来,中国的油气勘探不断发展,概括起来有四大新发现:①由于新构造运动控制晚期成藏,在渤海海域浅层发现石油地质储量超过亿吨级的油田群;②中西部地区山前冲断带油气勘探取得重大突破;③在塔里木盆地北部轮南隆起发现中国目前最大的奥陶系碳酸盐岩油田;④天然气勘探有突破性进展,探明储量大幅度增长。在塔里木库车坳陷、鄂尔多斯盆地中部、四川盆地东北部共获得三个重大发现并形成三个天然气富集区。这四大新发现,对我们未来的油气勘探有着重要启示。对近期油气突破领域的研究表明,中国的油气勘探领域是广阔的,同时也使我们树立了对中国未来油气勘探发展的信心。

THE RECENT NEW DISCOVERIES OF OIL AND GAS FIELDS IN CHINA AND THEIR IMPLICATIONS

In recent years China’s petroleum exploration moves forward quickly,generallyachieving the following four discoveries:(1)oil fields with reserves over 1.7 billion tons(Bt)in the shallow layer of the offshore Bohai Bay Basin;(2)great discoveries in the thrust belts of western China;(3)the Chinese largest carbonate reservoir field found in the Lunan Uplift of northern Tarim;and (4)several large gas fields with large reserves in western China, especially in Kuqa Depression of Tarim basin,central part of Ordos basin and northeastern Sichuan basin.The above oil and gas discoveries bring forward and important inspiration that China has large area worth exploring.In the coming 5~10 years,China’s hydrocarbon exploration will be prospective.
