【摘要】 地震反演技术能够大幅度提高地震资料分辨率,最大限度地挖掘地震资料所蕴涵的极其丰富的岩性、物性信息,是目前寻找隐蔽油气藏的有效手段之一。模拟退火波阻抗反演通过模型空间范围内广泛搜索寻求全局最优解,可以明显提高反演剖面的分辨率。利用ISIS模拟退火波阻抗反演技术,对苏北盆地高邮凹陷曹庄地区戴南组岩性储层进行精细预测,较好的描述了戴南组3个主要岩性储层发育段砂体平面展布规律。更多还原

【Abstract】 The seismic inversion,which is one of the effective techniques for searching for sublle oil/gas traps,can enhance the resolution of seismic data greatly and extract abundant lithological and physical information involved in seismic data to the maximum.Simulated annealing wave impedance inversion pursues the comprehensive optimal solution widely in the space scope of the model,which can enhance the resolution of the inversion section markedly.The lithological reservoirs in the Dainan Formation in the Caozhuang area,Gaoyou subbasin, Subei basin,were predicted in detail by the ISIS3D simulated annealing wave impedance inversion technique. The results better describe the plan distribution characteristics of sands of three main lithological reservoirs in the Dainan Formation.更多还原
