【摘要】:由于地震疊后數(shù)據(jù)識別小斷裂和裂縫帶難度較大,因此,圖像增強技術逐漸應用于地震處理和解釋中;贑ontourlet變換的圖像增強技術具有多尺度分解和多方向濾波的特點,可以很好地突出地震疊后數(shù)據(jù)中隱含的各向異性。通過地震物理模擬分析,并與其他技術相比,發(fā)現(xiàn)其在凸顯小斷裂和構造裂縫帶分布方面具有明顯優(yōu)勢。該項技術已成功應用于實際生產(chǎn),在復雜構造斷裂解釋和裂縫型儲層井位部署中發(fā)揮了重要作用。
[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.
