Abstract: In the light of evolutionary characteristics of deposition and structures in the course of ItS formation and development,the basin is divided into 4 structural zones of the 1st order: the main fault bending zone in the western part; the central fault foldng zone; the minor fault bending zone in the eastern part and the overlap folding zone on the margin.The first three zones constitute the main body of the basin.Local structures are classified from the view point of dynamics.After a synthetic study of the depositional characteristics of lake basins,their structural features anal types of oil pools,three ring-like zones of distribution of oil and gas fields with reservoirs of medium and shallow depth are proposed: inner zone with lithologic pool; middle zone with structural oil pools and outer zone with scattered oil pools.Prospects for each of these zones are reviewed,and a preliminary discussion of targets for exploration at depth is made at length.

摘要： 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.
