摘要
提出可直接预测油气藏分布的地震解释技术 :提取尽可能丰富的地震属性参数 ;首先对地震属性参数进行平滑处理 ,剔除异常值 ;再通过K L变换去掉与油气相关性差的属性参数 ,保留地震属性对油气响应的主要特征 ;然后用井旁已知的含油气信息与地震属性参数的关系标定地震剖面 ,预测井间油气分布 ,用地震油气分布预测剖面展示剖面的含油气预测结果。在松辽盆地北部某地区应用该技术预测含油气性 ,成功率达 90 %左右 ,说明该方法的应用效果良好。
This paper brings forward a new technology, which can directly forecast oil gas field. Firstly, seismic attribute parameters were picked up, exceptional data in it were eliminated by smoothness process, relativity between parameters were got rid of and primary characters were remained by K L transform; secondly, known oil gas information and seismic attribute parameters of well were used to forecast oil gas distribution; and finally, oil gas forecast result was shown by section. Forecast in Songliao basin indicates that this technology's success ratio is about 90%, and it has good application result.
