摘要: 锦州25-1油田是渤海海域近期发现的大型轻质油气田,是目前为止渤海海域最大轻质油气田,也是辽西凹陷首个亿吨级油田。油藏主要目的层段为古近系沙河街组,圈闭类型为复杂断块圈闭,具有完美的储盖组合,油藏具有埋深浅、储量大、丰度高、原油密度轻、测试产能高等特点,是一个整装大型油田。该油田的发现不仅带来储量上的增长,也为辽东湾勘探带来许多启示和思考,这些启示和思考比发现本身更为重要。

Abstract: Jinzhou 25-1 Oilfield is a large-scale light oil & gas field discovered recently in Bohai Sea Area. So far it is the largest one in the area, and it also is the first hundred-million-ton oilfield in Liaoxi Sag. The main interval of interest in the oilfield is Shahejie Formation in Paleogene. This oilfield is composed of a lot of complex fault-blocks with perfectly reservoir-gap combination. Jingzhou25-1 oilfield is a large scale self-contained oilfield with the characteristics of shallow burying, large reserves, high petroleum abundance, low density and high deliverability. The discovery of this oilfield will not only enlarge the reserves, but also bring a lot of enlightenment of hydrocarbon prospecting to Liaodong Bay which may be more important than the discovery itself.

Key words: light oil & gas field, Paleogene, prospecting enlightenment, Jinzhou 25-1, Bohai Sea
