摘要
研究了白音查平凹陷石油地质基本特征，指出该凹陷腾格尔组生油条件良好，烃源岩有机质丰度较高、具较强的生烃能力，与邻区凹陷相比较，该凹陷生油岩质量优于额仁淖尔凹陷；凹陷内区域性盖层发育，油气保存条件好，烃源岩大量排烃期处于断裂活动期之后，油气可保存在生油区附近的扇三角洲砂体中。文中对该区的有利勘探目标进行了预测，认为：①扇三角洲砂体邻近生油区，是有利的储集体；②腾格尔组的生储盖配置好，是有利的勘探目的层；③有利勘探目标分布在西部洼陷白音断层和塔拉南断层下降盘；④白音查干凹陷与额仁淖尔凹陷的油气成藏基本条件各有优劣，二者的勘探前景相当。
On the basis of a comprehensive analysis of the petroleum geological conditions in the Baiyinchagan sub-basin,the prospective area has been evaluated and conclusions have been made as follows: (1 ) The fan-deltaic sandbody,which is distributed near the source area,is the favorable reservoir.(2) The Tenggeer Formation is likely to be the petroliferous bed for its source,reservoir and seal rock are in a good assembly. (3) The prospective targets are distributed on the hanging wall of the Baiyin fault and the SOuthern Tala fault in the West sag of the sub-basin. (4)Prospects for hydrocarbon exploration in the sub-basin might be similar to those in the Errennaoer sub-basin.
