【摘要】 低级序断层具有延伸短、断距小的特点,加之复杂断块的断裂系统复杂,地震资料品质差,信噪比低,因此利用常规地震资料对低级序断层进行识别和组合的效果不是很理想。研究主要是利用基于小波变换的多尺度边缘检测技术对低级序断层的识别进行讨论。通过在复杂断块X15断块的应用结果表明:基于小波变换的多尺度边缘检测技术可以对复杂断块的低级序断层进行正确识别,从而为解决一些长期困扰开发地质人员的问题,为剩余油富集和分布的研究提供了非常宝贵的基础资料,为开发上的完善注采系统、合理井网加密提供依据。更多还原

【Abstract】 Low-level sequence faults had the characteristics of short expansion and small fault distances and as well as complex fracturing system of a complex fault with poor quality of seismic data and low signal-noise ratio,therefore identification and combination of low-level sequence was not very effective by using conventional seismic data. The identification of the low-level sequence faults by using multiscale edge detection techniques based on wavelet transform. The application results of complex Fault Block X15 show that,multi-scale edge detection technology based on wavelet transform can correctly identify the low-level sequence faults block,therefore,it can solve a long troubled problem for reservoir development,provide basic information for studying the remaining oil accumulation and distribution and for perfecting and infilling the injection-producing well patterns.更多还原
