| 摘 要： | 自松辽盆地开展地震勘探以来，T2断层就是一个永恒的话题，但T2断层的“假逆”现象引起人们的重视却是近年的事情。研究发现，这一现象的产生主要有两方面的原因：一是地震测线与断层走向斜交；二是由于T2断层处的岩性组合特点，在晚白垩世以来的区域挤压背景下在断层附近形成一个岩性过渡带的地震响应。

| Abstract: | T_2 Fault has always been discussed since seismic prospecting was carried out in Songliao basin;but until recently do people pay attention to pseudo reversion of T_2 Fault.Research shows there are two main causes for pseudo reversion of T_2 Fault: firstly,seismic line is diagonal to fault trend;secondly,characteristics of lithologic association of T_2 Fault form a seismic response to lithology belt of transition near fault in the regional compound background in later Cretaceous stage. |
