| 摘 要： | 四扣洼陷下第三系发育了沙河街组沙四上段、沙三段和沙一段三套烃源岩，其中沙三段是该区最重要的优质烃源岩；沙一段为低成熟烃源岩；而沙四上段烃源岩分布局限。油源对比显示渤南油田的原油主要来自沙三段烃源岩，义东油田的原油主要来自沙一段和沙三段烃源岩，罗家油田的原油主要来自沙三段和沙四上段烃源岩。 |
| 关 键 词： | 四扣洼陷 烃源岩 成熟度 油源对比 |

| Abstract: | 3 series of hydrocarbon source rocks, including Sha4 upper Member, Sha3 Member and Sha1 Member in Shahejie Formation, are developed in low Tertiary of Sikou sag. Sha3 Member is the most important good hydrocarbon source rock in this area; Sha1 Member is low mature hydrocarbon source rock; Distribution of hydrocarbon source rock in Sha4 upper Member is limited. According to oil and source correlation, the oil in Bonan oilfield mainly comes from the hydrocarbon source rock in Sha3 Member, oil in Yidong oilfield mainly comes from those in Sha1 Member and Sha3 Member, and oil of Luojia oilfield mainly comes from those in Sha3 Member and Sha4 upper Member. |
| Keywords: | Sikou sag hydrocarbon source rock maturity oil and source correlation |
