| 摘 要： | 沙沟油田是在靖边范围勘探程度较高的情况下发现的百万吨油田,它的发现对延安组油藏的发现有一定的指导意义。本文主要从成藏角度对沙沟油田进行阐述,指出油田圈闭以构造—岩性为主,单斜背景下发育的次级低缓鼻状构造对油气聚集具有控制作用;河道块状砂岩具有较好的粒度结构和胶结类型,是本区最有利的储集砂体。

| Abstract: | Shagou oilfield is a million-ton class oilfield which has been discovered in jingbian area. The discovery has some guiding significance to the reservoir in Yan＇an Formation. Structure-lithology trap is the main type of trap in this area. It＇s indicated that sub-nose-like structure under the monoclinic structure has control action to the oil accumulation, and channel massive sandstone which has preferable grain size structure and cementation type is the most favourable reservoir sandstone. |
