| 摘 要： | 济源凹陷为一个中新生代沉积断陷，具有良好的油气勘探远景。凹陷内油藏形成条件具有下列特征：（1）中生界生油岩有机质丰度高，母质类型较好，热演化程度高；（2）下第三系储层发育，但以中低孔渗储层为主；（3）局部构造发育，圈闭类型多，以后邓构造最有利；（4）邓2井油藏属于以中生界为油源岩、下第三系为储集层的古生新储断块油藏。

| Abstract: | Jiyuan Sag is a fault-subsided Meso-Cenzoic Sag, which possesses a good explorationprospect of oil and gas. The formative conditions of its reservoir showed following characteristics: (1 )Theresource rock contains rich-organic material with good keroger pattern and high thermal maturity. (2) Tertiary reservoir rock abounds and is mainly composed of medium-low porosity and permeability one. (3) Local structure is the most prospective. (4) Den 2 reservoir is a fault-block reservoir with Mesozoic resourcerock and Teriary reservoir rock. |
