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 section patterns can be divided into flat, plow and slope-type, with the different sections of the pattern fold traction fold, reverse traction fold, rolling fold and composite fold. In the past, people had mixed reverse traction folds and rolling folds, creating a degree of confusion. In this paper, we analyzed the two fold styles from the genesis, and pointed out their distinguishing marks. Finally, the significance of oil and gas exploration for the associated faults of the normal faults is discussed.
