摘　　要：断层解释是开展储层研究工作的重要环节之一,但是受构造背景及地震资料质量的影响,在常规地震剖面上直接解释断距小于λ/4的断层系统比较困难,使得地下储层的情况并不为解释人员所了解,因此,为了有效识别研究区的小断层系统,为断层的解释工作做出指导,本文在具体分析研究区断层识别能力的基础上,利用体属性、沿层构造属性及目的层吸收衰减属性对研究区A的断层系统进行了有效预测,并取得了较好的研究效果。Fault interpretation is an important part in the research of reservoir, but under the influence of structure background and the quality of seismic data, it is difficult to explain the fault system which is less than λ/4 in the conventional seismic section. Therefore, in order to identify small fault system effectively in the study area, and make a guidance for interpretation of faults, based on the analysis of the fault＇s identification ability in research area, the fault system of area A is effectively predicted by body attribute, layer＇s structure attribute and target layer＇s absorption attenuation attribute, which has achieved good results.
