| 摘要: |
| 本文以测井相为手段,通过对渤中25-1南油田某评价井粒度资料的分析,揭示了浅水三角洲各微相的粒度特征,并在此基础上对不同微相和同一微相不同部位的粒度特征进行了比较,阐述了差异的原因。分析结果表明,浅水三角洲的粒度累计曲线形态和粒度C-M图特征有别于曲流河和普通河控三角洲,体现了浅水三角洲独特的水动力特征。 |

| Abstract: |
| The shallow-water delta is a special type of deltas.Examplified by one well Well A in the Bozhong 25-1 Southern Oil Field,the present paper deals with the grain size analysis and correlation for individual shallow-water delta microfacies.These grain size analyses show that the grain size probability cumulative curves and C-M patterns for the shallow-water deltas quite differ from those for the meandering streams and river-dominated deltas,suggesting the unique hydrodynamics of the shallow-water deltas. |
