| 摘 要： | 尼日尔研究区阿格巴达组(Agbada)压实程度相对较小,声波响应特征值小。测井资料广泛应用于地震反演,曲线重构是提高储集层与围岩速度差异不明显地区测井约束地震反演效果的有效技术。因该区声波测井资料匮乏,需要拟合声波曲线用于地震反演。文中简单介绍了测井资料的处理,对具有声波曲线井做测井交会图分析,阐述了同一沉积环境下的相同岩性的声波曲线以低频信息和高频信息相融合并参考地层岩性参数的拟合方法,对拟合的伪声波曲线做了对比分析并应用于储层反演。

| Abstract: | Agbada Group,the research region in Niger,is under,compacted and acoustic logging response value is small.Well logging data are widely used in seismic inversion.Log reconstruction is an effective technique which can improve the inversion effect constrainted by well logging in the areas where there is little difference in velocity between reservoirs and surrounding rocks.Because there are less acoustic logging data about this area,it is necessary to reconstruct acoustic logs used in seismic inversion.This pa... |
