断陷湖盆辫状河三角洲沉积特征与模式探讨——以渤海湾盆地岐口凹陷为例

Model and sedimentary characteristics of braided river delta in faulted basins: A case from Qikou Sag in the Bohai Bay Basin

为了深化对断陷湖盆辫状河三角洲沉积地质的认识,促进该类盆地的油气勘探,本文以渤海湾盆地岐口凹陷为例,充分利用岩心观察、粒度分析以及测井资料对断陷湖盆辫状河三角洲的沉积特征与演化模式进行了深入分析。

The geological knowledge of braided river delta in faulted basins will be of important significance for oil and gas exploration. Taking Qikou Sag in the Bohai Bay basin as an example,the data of core,grain analysis and logging were used to study the sedimentary characteristics and evolution model of braided river delta in faulted basin.
