【摘要】 本文基于海拉尔盆地乌东地区三维地震资料,通过构造应力场分析、叠前地震属性方位各向异性分析和叠后地震衰减属性分析等方法,对该地区的裂缝储层进行了预测。利用叠后裂缝属性和构造应力场分析对宏观裂缝发育带进行了定性预测,总结出乌东地区裂缝方向以北北西向和北东东向为主,并利用叠前地震属性方位各向异性定量预测了该区裂缝密度。更多还原

【Abstract】 Based on the 3D seismic data in Wudong Area of Hailar Basin,the fracture reservoir was predicted in this area by using several methods,such as tectonic stress field analysis,pre-stack seismic attribute azimuth anisotropy analysis,post-stack seismic attenuation attribute analysis and so on.The qualitative prediction for the macroscopic fracture development zone was conducted by using post-stack fracture attribute method and the tectonic stress field analysis method,it was found out in the study that the fracture orientation is mainly in NNW and NEE direction,the fracture density was quantitatively predicted by using pre-stack seismic attribute azimuth anisotropy analysis method.更多还原
