摘　　要：改造型含油气盆地是指含油气盆地原型经过内外地质动力作用使其面貌发生了重大改变的盆地。根据内外地质动力作用方式将其划分为抬升改造型 ,块断改造型和冲断、褶皱改造型三类。勘探改造型盆地油气的技术路线不能仍然依照“定凹选带”的原则 ,应建立新的“晚期成藏、成藏单元与整体持续封存”的研究思路与方法 ,将改造型盆地成藏单元划分为改造破坏型、改造保存型与改造建设型三种类型 ,只有后二种类型的成藏单元才具有油气勘探价值。Reformed petroliferous basins are those that the feature of the prototype basins have changed greatly under inner and outer geological dynamics.According to different geological dynamics,the reformed basins could be divided into three types:(1)uplift-reformationtype;(2)fault-block reformationtype,and(3)thrust-fold reformationtype.The thinking and method for the exploration of reformed basins should not always use the principle of “determining depression and selecting zone”,but establish a new research thinking of “late pool-forming,pool-forming unit and integral continuous sealing”,and divide the pool-forming units of the basins into reformation-destroying,reformation-preserving and reformation-building types.The last two kinds of pool-forming units are favourable for hydrocarbon exploration.
