【摘要】:由于地震叠后数据识别小断裂和裂缝带难度较大,因此,图像增强技术逐渐应用于地震处理和解释中。基于Contourlet变换的图像增强技术具有多尺度分解和多方向滤波的特点,可以很好地突出地震叠后数据中隐含的各向异性。通过地震物理模拟分析,并与其他技术相比,发现其在凸显小断裂和构造裂缝带分布方面具有明显优势。该项技术已成功应用于实际生产,在复杂构造断裂解释和裂缝型储层井位部署中发挥了重要作用。
[Abstract]:Because it is difficult to identify small faults and fracture zones by post-stack seismic data, image enhancement technology is gradually applied to seismic processing and interpretation. The image enhancement technology based on Contourlet transform has the characteristics of multi-scale decomposition and multidirectional filtering, which can highlight the anisotropy implied in post-stack seismic data. Through seismic physical simulation analysis and compared with other techniques, it is found that it has obvious advantages in highlighting the distribution of small faults and structural fracture zones. This technology has been successfully applied to practical production and has played an important role in complex structural fault interpretation and fracture reservoir well location deployment.
