摘　　要：在地震和电法解释基础上,结合区域构造特征,将平岗—辽源盆地白垩纪以来的盆地构造演化划分为断陷、坳陷、挤压逆冲3个阶段。通过进一步分析盆地沉积充填对烃源岩、储层和盖层形成的影响,认为残留盆地成藏的主控因素是烃源岩条件和保存条件。根据盆地演化和沉积充填特征的综合分析,指出云顶凹陷区、泉太凹陷和共安凹陷为有利勘探区。On the basis of regional tectonic characteristics and interpretation of seismic and electric methods, the tectonic evolution of Pinggang -Liaoyuan Basin can be divided into fault depression, depression, compression and thrust since Cretaceous. Sedimental filling in the basin influenced on hydrocarbon source rocks, reservoir and caprock through the further analysis. The main controlling factors of residual basin reservoir formation were the con- ditions of the hydrocarbon source rocks and preservation. According to the basin evolution and sedimental characteristics, we consider the Yunding-, Quantai- and Gongan sags as favourable areas for exploration.
