| 摘 要： | 河流相储层是一种重要的储层类型,寻找河道砂体是油气勘探的一项重要工作。但是河道变迁比较频繁,叠置比较严重,加之地震资料本身信噪比和分辨率的限制,河流相储层的精细描述至今仍存在一定的困难。本文以胜利油田老河口三维工区为例,首先研究了本区河流相储层的基本特征,发现该类储层剖面上呈强相位、切片上连续性好和频谱上呈低频特征;通过颜色处理和地震精细解释,发现本区河流相储层存在类串珠状特征,为了验证这一观测结果,我们用正演模拟分析了其形成机理,为在类似工区识别此类古河道找到了新的途径;应用多属性融合和RGB显示技术,河道下切特征更加明显,很好地彰显了河道结构特征,提高了河道识别能力;最后,我们研究并开发了多子波检测技术,检测出更多河流相弱反射信息。

| Abstract: | Finding channel sandbodies is an important task in oil and gas exploration due to the importance of fluvial reservoirs.It is difficult to describe fluvial reservoirs in detail owing to their frequent changes and serious intersections,as well as limitations of S/N ratio and seismic data resolution.Based on the Laohekou 3D data in Shengli Oilfield,we analyze the general characteristics of fluvial reservoirs in this area,from which we find that they are characterized by strong amplitudes on seismic profiles,hi... |
