谱蓝化技术在大王庄油田储层预测中的应用

Application of spectral bluing frequence technology in reservoir prediction of Dawangzhuang area

大王庄沙二段储层以滩坝砂岩为主,储层厚度薄且横向展布变化较快,储层预测难度大。针对该问题,利用谱蓝化技术对地震资料进行拓频处理,有效地拓宽了地震的频带,增强了高频信息的地震响应,提高了薄储层的地震分辨率。将该方法用于大王庄地区滩坝砂岩薄储层的地震描述,有效预测了砂体的展布和联通性,为该区块勘探开发提供了依据。

The main reservoir type is beach bar sandstone in Es_2 formation in Dawangzhuang area. The thickness and horizontal distribution of reservoir change rapidly,and its prediction is difficult. In order to solve this problem,the spectral bluing frequency technology is used for frequency broadening processing. This method can enhance the high frequency information of seismic and improve the seismic resolution of thin reservoir effectively. It has been used for seismic description of the beach bar sandstone reservoir in Dawangzhuang area. It can predict sand distribution and connection effectively and provide favorable bases for the EP of the area.
