本文用综合评价方法对准噶尔盆地东部东道海子北一五彩湾凹陷及白家海凸起斜坡带石炭一休罗系的储盖层特征进行评价,将其评价结果在纵向上进行组合,划分出若干套储盖组合。认为J1s中上部/J1s底部、J1ba上部/J1ba下部组合最为重要,其余组合次之。根据储盖组合分布特点对研究区储盖组合进行了面上预测及评价。

By means of comprehensive evaluation method, the characteristics of Carboniferous-Jurassic reservoirs and mantles in the North Dengdaohaizi-Wucaiwan Depression and Baijiahai convex slope zone of East Junggar Basin are evaluated. After the combination of the results longitudinally, several sets of reservoir and mantle assemblages are recognized. It is considered that the assemblages of M. U. J1s/L. J1s and U. J1ba/L. J1ba are most important, and the other assemblages are of secondary importance. Based on the distributive features of reservoir and mantle assemblages, the reservoir and mantle assemblages of the study area are predicted and evaluated on-plane.
