摘要

准噶尔盆地南缘头屯河组中段作为重要的油气储层,其沉积类型尚存争议。通过头屯河组露头的岩相、岩相组合特征分析及剖面精细解释,识别出9种岩相和4种岩相组合,岩相组合类型在垂向上具有二元结构特征,剖面上侧积现象明显,为曲流河的点坝序列,证实头屯河组中段为曲流河沉积。实测结果表明,曲流河点坝的单期侧积砂体厚约为3~5m,宽约为90~120m,倾角约为5°;侧积泥厚约为50cm,倾角约为3°~6°。基于露头研究结果,探讨了曲流河侧积成因砂体“先单井识别、后井间预测”的对比方法及步骤,指出了关键参数的求取方法,为曲流河地下储层的精细构型表征提供了定量化基础数据。

Abstract

The middle member of Toutunhe Formation in southern margin of Junggar Basin is an important hydrocarbon reservoir,while the type of depositional system is still controversial.Based on detailed analysis of outcrop lithofacies and lithofacies associations and fine interpretation of outcrop section,nine lithofacies and four lithofacies associations were identified.Typical lithofacies association was characterized by dualistic structure,and obvious lateral accretion was identified in outcrop sections,which can be confirmed as point bar sequence of meandering river.It proved the existence of meandering river in the middle member of Toutunhe Formation in southern margin of Junggar Basin.According to measured results,thickness of lateral accretion sandbody in the middle member of Toutunhe Formation was about 3-5m,about 90-120m wide,with an angle about 5°.Laterally accreted mud was about 50cm thick,with a dip of 3°-6°.Based on the results of outcrop study,correlation method and steps of “identified in single wells first and predicted among wells second” for lateral accretion sandbodies in meandering river have been discussed,providing a quantitative geological knowledge base for the correlation of underground sandbodies developed in meandering river.
