摘　　要：断层是一个有宽度的"带",但一般对其简化为"线"、"面"处理,因此断层破碎带的结构、性质、纵横向变化的研究较欠缺。笔者通过在胶莱盆地、鲁西隆起、南华北盆地等张性断裂发育区进行露头剖面描述工作,对不同级别断层的断距、断层破碎带等考察,对其厚度、宽度和发育产状等进行丈量,对断层破碎带进行纵横向追踪。认识到无论断层的性质、规模如何,在露头上都以破碎带接触。由于断层的性质不同,断层破碎带的内部结构有所不同;断层的规模不同,破碎带的宽度不一,小至1米之内,大至上千米。在详细观测描述研究的基础上,建立了断层破碎带完整的结构特征露头模式,对断块油田地下断层破碎带研究具有指导意义。The fault is a zone with width,however,it is always simplified as line and surface in the field work,therefore,the study on structure,property and lateral extending of fault breakage zone is still not completed.Herein,we surveyed the extending faults developed in the Jiaolai basin,Luxi uplift and south Huabei basin,and measured the thickness,width and developing occurrence of different scale of throw and breakage zone in the fault,and traced the longitudinal and transversal breakage zone.It is revealed that the outcrop is shown by the breakage zone that is indicative of the existence of fault regardless of scale and property of fault.Due to the fault property,the internal structure of breakage zone is varied,as well as the width of breakage zone due to the scale of fault,ranging from 1m to more than 1000m.Based on the detailed description,the outcrop mode of breakage zone is proposed herein to instruct the study on breakage zone in the fault block oilfield.
