Fault zone refers to the fracture zone in the stratum, which is of great significance to the migration and accumulation of hydrocarbons. Each fault zone has a unique, complex structure. Hence, the hydrocarbons migrate and accumulate differently from fault zone to fault zone. The accurate division of fault zone structure is critical to understanding fault-controlled hydrocarbon reservoirs. Currently, the fault zone structure is often roughly identified by logging, based on a summary of fuzzy response modes. The innovation of this paper lies in the following: according to the macro- and micro-characteristics of structural units with different lithology, different logging responses, and core data in Jiyang Depression, a fault zone structure identification method based on wavelet attributes of logging data is proposed. Through multi-scale processing, the proposed method reconstructs and highlights the high-frequency information of curve fluctuations on the appropriate scale, enabling the accurate identification of fracture development intervals. Taking Che-57 well which passes through fault zone in Jiyang Depression of Shengli Oilfield as an example, the structure of fault zone is identified by wavelet attribute. The results show that the three porosity wavelet attributes could accurately characterize the structure of the fault zone; the sliding fracture zone has a low frequency and a low amplitude; the induced fracture zone has a high frequency and a high amplitude; the density and acoustic wavelet attribute are more sensitive than the electrical curve. The research results shed new light on the identification of fault zone structure in carbonate stratum.

断裂带是指地层中的断裂带，对油气运聚具有重要意义。每个断层带都有独特而复杂的结构。因此，从断层带到断层带，油气运移和聚集是不同的。断层带结构的准确划分对于理解断控油气藏至关重要。目前，基于模糊响应模式的总结，通常通过测井粗略识别断层带结构。本文的创新之处在于：根据济阳坳陷不同岩性、不同测井响应、岩心资料的构造单元的宏观和微观特征，提出了一种基于测井资料小波属性的断裂带构造识别方法。被提议。通过多尺度处理，提出的方法在适当的尺度上重构并突出了曲线波动的高频信息，从而能够准确识别裂缝发育层段。以胜利油田济阳凹陷车57井穿越断裂带为例，利用小波属性识别断裂带结构。结果表明，三种孔隙度小波属性能够准确表征断裂带的结构；滑动断裂带频率低，振幅低；诱导断裂带频率高，振幅大；密度和声小波属性比电曲线更敏感。研究成果为碳酸盐岩地层断裂带结构的识别提供了新的思路。
