通过对研究区沉积层序、岩芯特征、粒度特征、测井资料及录井资料的详细分析，对比总结了该地区的沉积模式和序列特征，研究表明地层抬升，气候潮湿，雨量充沛，造成西北部物源供应大，八道湾组沉积早期，研究区以辫状河沉积体系为主，随后，物源供应下降，加之快速湖侵，过渡为辫状河三角洲及湖泊沉积体系。
通過對研究區沉積層序、巖芯特徵、粒度特徵、測井資料及錄井資料的詳細分析，對比總結瞭該地區的沉積模式和序列特徵，研究錶明地層抬升，氣候潮濕，雨量充沛，造成西北部物源供應大，八道灣組沉積早期，研究區以辮狀河沉積體繫為主，隨後，物源供應下降，加之快速湖侵，過渡為辮狀河三角洲及湖泊沉積體繫。

Through to detailed analysis the sedimentary sequence,core characteristics,granularity characteristics,and logging data in the study area,contrast and summarizes the sedimentary pattern and sequence characteristics of the region. It has shown that with strata uplifting,humid climate and aboundant precipitation caused a large amount of supply from northwest provenance. Early sedimentary period of Badaowan forma-tion,braided river sedimentary system developed mainly in the area. Aftertime,the former was transited to braided river delta and lake diposi-tional system because of decreasing supply of sediment and lake transgression.
