摘要
///Songliao Basin is a large-sized fiat basin with two kinds of normal-reversal tectonics. Controlled by deep faults and basement faults, the reversal tectonics are horizontally characterized by two zones and belts： east and west and furthermore by south and north blocks. Influenced by the reversal tectonic movement, unique large-scaled tectonic windows on the top of Daqing Placanticline and Changchunling anticline axis are formed, thus the favorable conditions for uranium and oxygen-bearing water infiltration have created. Qnl-2 and N2 are main oil-generating rocks Hiyupao-Toutai Fault Zone and Qixi-Aogula-Halahai Fault Belt throughout the basin are not in Daqing oilfield.
