| 摘 要： | 本文以岩石学及沉积学为理论指导,以孤南30井沙三段的岩心、钻井、测井、录井、试油等资料为基础,对孤南30井沙河街组沙三段岩石地层的划分展开了研究,并寻找其有利储集层。研究表明:孤南30井沙河街组沙三段主要发育河流和湖泊两种类型沉积相,可分为4个砂层组,10个小层;沙三段中下部沉积水体较深,泥岩与砂岩互层,砂体含量增高,有利于形成良好的储集层,又发育有厚层灰质油泥岩,形成了较好的生储盖圈闭。

| Abstract: | Study of the core, drilling, logging, logging and oil testing data indicates that the Third Member of the Shahejie Formation in Gunan 30 well, Gunan Sub-sag may be divided into 4 sand-bed groups and 10 sub-layers, belonging to fluvial facies and lacustrine facies. The lower part of the Third Member of the Shahejie Formation is alternating beds of mudstone with sandstone rich in sand bodies and thick lime oil-bearing which are favorable for forming good reservoir and better source-reservoir-cap trap. |
