| 摘 要： | 国内外油气勘探实践表明,含盐盆地的油气富集和分布与盆地内沉积的盐岩密切相关。东濮凹陷是我国东部地区典型的含盐油气富集盆地,作者通过深入研究其地层层序特征及盐岩纵横向分布特点,进一步剖析了盐岩沉积的主要控制因素及其与生储盖层的关系,搞清了含盐盆地油气的分布和富集与盐岩的关系,指出无论在垂向上还是横向上,东濮凹陷盐岩一般都与暗色烃源岩共生,而且盐岩与同期沉积的砂岩表现为长消关系。研究认为盐岩可作为油气上盖或侧向遮挡,与源岩、储集层可组成良好的生储盖配置关系,利于油气富集区带的形成,对构造和隐蔽油气藏的形成都发挥了积极的作用,并指出与盐岩有关的文东北部和胡状集地区是下一步挖潜的有利勘探方向。研究成果也可为国内外同类含盐盆地的油气勘探提供一定的借鉴经验。

| Abstract: | The practice of hydrocarbon exploration at home and abroad shows that oil and gas enrichment and distribution are in close relation to salt rock deposited in the basin. This paper goes into the characteristics of the stratigraphic sequence as well as salt rock distribution vertically and horizontally in Dongpu depression, which is one typical oil enrichment salt-contained basin in the east of China, further analyses the main controlling factors of salt deposition and its ties with resource rock,reservoir rock and capping bed, points out that whether vertically or horizontally, salt rock and resource rock grow together, and that salt rock behaves as advance and retreat relation with the homochronous deposited sand rock. Salt rock can hold up hydrocarbon in up and lateral direction, can form a good trap for hydrocarbon accumulation. The north of Wendong and Huzhuanji area, which bear salt rock, are believed to be the favored exploration zone for further development. The research findings in this paper can also give some reference for oil prospecting in the similar salt basin at home and abroad. |
