摘　　要：正断层断面样式可分为平面式、犁式和坡坪式，与不同断面样式相伴生的褶皱有牵引褶皱、逆牵引褶皱、滚动褶皱和复合褶皱。过去人们把逆牵引褶皱和滚动褶皱混为一体，造成一定程度的混乱。本文从成因上分析了这两种褶皱样式，指出了它们的区别标志。最后讨论了正断层上盘伴生褶皱的油气勘探意义。Normal fault plane pattern can be divided into planing,listric and sloping style. The folds associated with different fault plane pattern are drag fold, reverse drag fold,rollover fold and complex fold. People mixed reverse drag fold with rollover fold together in the past. It caused a confusion to a certain degree. The paper analyzed these two fold styles from contributing factors, pointed out their identified marks and discussed the meaning of folds associated with upside of normal fault in oil-gas exploration.
