摘要
以往对东海陆架盆地的油气勘探主要集中在东部坳陷带的西湖凹陷 ,目的层主要为下第三系。西部坳陷带虽然第三系厚度薄 ,但中生界和古新统厚度大 ,分布广 ,具有良好的油气生、储、盖、圈、运、保条件 ,可能成为下一步的勘探目标。
Previous petroleum explorations in the East China Sea shelf basin were concentrated on the Paleogene of Xihu depression in the eastern depression zone. Although the western depression zone has a thinner Tertiary, its Mesozoic and Paleocene are thicker and more widely distributed. Its good conditions of oil generation, reservoir, capping, migration, and preservation will make the western depression the next target in the future explorations.
