分频技术在大庆高台子油田扶扬油层储层预测中的应用
|
摘要
为了解决沉积相带的分区问题,利用分频技术研究不同的岩性组合模式产生不同的振幅谱响应的特点,在大庆高台子油田进行了储层预测分析.结果表明:振幅谱的频率响应具有对时间域的微小变化或差别更加敏感的特点,能够反映1/4波长厚度的储层信息.采用分频处理技术研究高台子油田河流相沉积储层的分布特征,不仅获取了厚层的砂岩信息,而且明显地反映出了厚度远小于地震分辨能力的薄砂岩的沉积规律,研究区可以划分为河道发育、摆动的区域和河道间为主的区域.研究结果与已知井吻合较好.
For the division of the sedimentary facies zones,the characteristics of the amplitude spectrum in response to different lithology combination is studied by using frequency-decomposing technology,which is applied to the reservoir prediction of Gaotaizi Oilfield.The result shows that the frequency response of the amplitude spectrum is very sensitive to the small change or difference in time domain,and it can reflect the reservoir information in the depth of quarter wavelength.According to the research results of the fluvial reservoirs in Gaotaizi Oilfield,the reservoirs can be clearly divided into the channel-developed region and the interchannel-developed region,which is consistent with the data from known wells.The information of not only thick sandstone layer but also much thinner sandstone layer than seismic resolution can be obtained by using the frequency-decomposing technology.The research result can be used for the exploration of the area.
