临南地区沙三段砂岩体及其成藏特征

Sba 3 sand and reservoir fonning features in Linnan area

从沉积环境的演化出发,探讨了临南地区沙三下段水下扇体、沙三上段河流三角洲、滑塌浊积体的发育特点及展布规律,进而结合临南地区构造、油源条件等,指出了不同砂岩体可形成多种类型油藏:断层河道砂油藏、断层扇体油藏、三角洲前缘滑塌浊积体透镜状油藏。结果表明:临南地区具有广阔的勘探开发前景。

This paper discusses the development feature and distribution law of underwater fan in lower Sha 3 formation, fluvial delta in upper Sha 3 formation, and slump turbidite in Linnan area. Incorporation of the structure and oil source shows that various reservoirs had formed due to different sands, namely fault channel sand reservoir, fault fan reservoir; and delta front slump turbidite lenticular reservoir, indicating broad prospects of exploration and development.
