摘要(Abstract)：

受地震资料纵向分辨率及成像质量的限制，传统断层解释技术难以满足油田开发对断层解释精度的要求。为了实现在三维空间上精准识别断层，通过密井网数据与高分辨率三维地震数据的协同融合，结合井断点信息，集成创新了精细断层解释技术。结果表明：利用高质量的方差体、蚂蚁体等构造属性体可有效识别断层空间展布特征；遵循“地震数据定框架，测井资料定细节”的指导原则，实现了井断点与断层面的精确匹配，构建了高精度断层模型；揭示了大断层下盘低速层导致地震反射同相轴上拉，产生逆断层特征的假象；结合二维地震正演模拟和分频解释技术，有效识别了井间低级序小断层，弥补了传统井断点引导小断层地震识别技术的不足；指出大断层破碎带内伴生小断层的存在，断层组合时简单将多个断点归为一个大断层是不准确的。研究成果可大幅提升断点组合成功率和断层空间识别率，为油田开发、措施调整及方案编制提供技术支撑。
Limited by vertical resolution and imaging quality of seismic data, traditional fault interpretation technique is difficult to meet the precision requirements for fault interpretation in oilfield development. In order to achieve accurate fault identification in three-dimensional space, fine fault interpretation technique is integratively innovated through the collaborative fusion of dense well network data and high-resolution 3D seismic data, combined with well breakpoint information. The results show that, spatial extention characteristics of the faults are effectively identified by using high-quality structural attribute volumes such as variance body and ant body. Following the guiding principle of “seismic data defining the framework, and logging data refining the details”, accurate matching of well breakpoints and fault surfaces is achieved to establish high-precision fault model, revealing that low-velocity layers under the footwall of large faults cause the uplift of seismic reflection events and the illusion of reverse fault characteristics. 2D seismic forward modeling and frequency-division interpretation technique are combined to effectively identify the small low-order inter-well faults, making up for the deficiency of traditional seismic identification technique of small faults guided by well breakpoints, pointing out the existence of associated small faults within the large-fault fracture zone and the inaccuracy of simply classifying multiple fault points into a large fault during fault combination. The research significantly improves the success rate of fault points combination and the spatial identafication rate of faults, providing technical support for oilfield development, measure adjustment and plan formulation.
