从松辽盆地形成与发育过程中的沉积和构造演化特征出发,将盆地划分为四个一级构造带:西部主断拗褶带;中央断隆褶带;东部次断拗褶带;边缘超覆褶带。前三者是盆地的主体。对局部构造,划分为三大环带。岩性油藏带(内带);构造油藏带(中带);零散油藏带(外带)。指出了各带的勘探前景。对深部地层的勘探方向进行了初步探讨。
Based on the sedimentary and tectonic evolution characteristics during the formation and development of the Songliao Basin, the basin is divided into four primary structural zones: the main faulted fold belt in the west, the central fault fold belt, the sub-fault fold belt in the east, Fold belt. The first three are the main body of the basin. The local structure, divided into three major zones. Lithologic reservoir zone (inner zone); Structural reservoir zone (middle zone); Fragmented reservoir zone (outer zone). Point out the exploration prospects of each belt. The exploration of deep strata has been preliminarily discussed.
