摘要
以BHH盆地ZHA地区为例,探讨了在缺乏钻井资料的条件下,如何充分利用现有地震资料,进行储层预测及烃类检测。结果表明,在做好地震资料“保真”处理的前提下,才能使提取的叠前、叠后地震属性更真实、可信;并综合利用叠后属性中的振幅、弧长、道积分等属性可以很清楚地刻画储层展布特征;利用频率、吸收系数及叠前AVO现象、泊松比变化等属性可以更好地预测油气异常,为钻探提供可靠依据。
In this paper,taking ZHA region of BHH basin as an example,study how to apply seismic data to predicate reservoir and oil-gas in the area where the well is little.It shows that pre-stack and post-stack seismic attributes are reliable base on preserved amplitude processing.The seismic attributes,such as amplitude,arc length and trace integration sections,are integrated to map reservoir character.The seismic attributes,such as frequency,absorption coefficient and AVO attribute,the changing of poisson ration,are applied to detect oil-gas-bearing trap.
