摘要
利用最新的鸡6井的分析化验资料以及已钻12口探井的数据,从纵向和横向上对鸡西盆地的烃源岩进行了重新评价。鸡西盆地白垩系的城子河组和穆棱组烃源岩有机质丰度相对较高,有机质大部分为Ⅲ型,少部分为ⅡB型;东山组和城子河组烃源岩达到成熟阶段,穆棱组烃源岩为未成熟到低成熟阶段。梨树凹陷烃源岩相对其它凹陷有机质丰度最高,梨树凹陷和滴道凹陷为有利勘探区。
Using newest examination data of Well J6 and data of existed 12 wells, this paper re-evaluates source rock in Jixi Basin vertically and horizontally. Source rock of Cretaceous Chengzihe Formation and Muling Formation in Jixi Basin have a high abundance of organic matter, being mainly type Ⅲ, and a little type ⅡB. Source rock of Dongshan Formation and Chengzihe Formation reaches to mature stage, and that of Muling Formation is immature-low mature stage. Comparing with other sags, source rock in Lishu Sag has maximum abundance of organic matter. Lishu Sag and Didao Sag are favorable exploration area.
