齐古组是准噶尔盆地具石油勘探潜力的地层单元,但有关该地层单元的沉积储集层特征研究较少,这种基础地质研究的欠缺成为阻碍该地区齐古组油气藏勘探开发的难点。以宏观钻测井及地震资料结合微观实验分析资料为基础,在高分辨率层序地层格架内,对阜东斜坡阜东16井区齐古组一段沉积特征(主要包括碎屑颗粒结构特征、岩芯和测井相特征以及沉积相平面展布)和储集层特征(主要包括岩石类型、储集空间类型、孔隙结构和储集物性特征)进行重点研究,认为齐古组一段岩性油气藏具有良好的勘探前景。
The Qigu Formation is a stratigraphic unit with potential for oil exploration in the Junggar Basin. However, few studies have dealt with the characteristics of sedimentary reservoirs in this stratigraphic unit. This lack of basic geological research has become a hurdle to the exploration and development of the Qigu Formation in this area. Based on the macroscopic drilling and seismic data combined with microscopic experimental data, the sedimentary characteristics of the first member of Qigu Formation (mainly including the features of detrital granulite structure) in the high-resolution sequence stratigraphic framework , Core and log facies features and sedimentary facies plane distribution), and reservoir characteristics (mainly including rock type, reservoir space type, pore structure and reservoir physical characteristics). It is considered that the lithology Reservoirs have good exploration prospects.
