| 摘要: |
| 潜江盐湖盆地是我国内陆独一无二的高盐度盐湖沉积盆地。本文在分析其岩性韵律特征的基础上,探讨了潜江盐湖生储盖组合特征。研究表明,潜江凹陷潜江组是在干湿频繁交替的古气候条件下,在高盐度、强蒸发、还原—强还原水体中,由北部单向碎屑物源及凹陷周缘卤水与盐源补给形成的盐系地层,岩性组合的有序变化形成了多套生储盖组合系统,不但反映出潜江盐湖沉积的特殊性和复杂性,而且具有十分优越的成油气地质条件。 |

| Abstract: |
| The Qianjiang salt lake basin is a lonely continental highsalinity lake basin in China.The characteristics of the source-reservoir-seal associations in the basin are examined in the light of rhythmic successions.The Qianjiang Formation in the Qianjiang depression is built up of a succession of clastic rocks,carbonate rocks and evaporites heaped up by the accumulation of the northernly debris and marginal brines and salt sources in the water bodies with high salinity,intense evaporation and reduction-strong reduction under the frequently alternating dry and wet palaeoclimatic conditions.The ordered alternation of lithologic associations allow the source-reservoir-seal systems to be developed,which constitute excellent conditions for hydrocarbon accumulation. |
