锦州25-1油田是近期发现的大型轻质油田,也是截至目前渤海海域发现的最大的轻质油田和辽西凹陷首个亿吨级油田。该油田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,具有良好的储盖组合;油藏具有埋深浅、储量大、丰度高、原油密度低、测试产能高等特点。锦州25-1油田的发现具有重要的地质意义。 Jinzhou 25-1 oilfield is a large-scale light oilfield recently discovered, and is also the largest light oilfield discovered in the Bohai Sea area to date and the first billion-ton oilfield in Liaoxi Depression. The main target section of this oilfield is Shahejie Formation of Paleogene. The trap type is complicated fault block traps with good combination of reservoir and cover. The reservoirs have shallow depth, large reserves, high abundance, low crude oil density, Higher characteristics. The discovery of Jinzhou 25-1 oilfield has important geological significance.
