摘　　要：二连盆地在腾二末期由张性应力场转变为压性应力场,为反转构造的形成创造了应力条件。不同凹陷或地区因地质背景不同,受力机制不同,形成的反转构造特征各异。对于二连盆地而言,形成于赛汉中期以前,反转程度较强烈,有主力烃源层阿尔善组地层卷入变形的反转构造,对油气运移和聚集最为有利。The tensional stress field was changed into a compressive stress field in the late depositional stage of Teng-2 formation in Erlian basin, which created stress conditions for formation of reverse structures. There are different reverse structures with different characteristis because of difference of geological background and force-accumulating mechanism in differential sags or regions. In Erlian basin, if reverse structure was formed before the middle depositional stage of Saihan formation, which inverted degree would be very intense; if the reverse structure was formed in a condition that the main source sequence-Aershan formation was involved in deformation, there would be much migration and accumulation of hydrocarbon.
