地层切片技术在深水湖底扇识别中的应用——以松辽盆地北部英台大安地区青山口组一段为例

The Application of Strata Slicing in Recognition Deep Sublacustrine Fan-as an Example of Qingshankou First Section of Yingtaidaan Area in the North of Songliao Basin

利用地震沉积学的地层切片技术并结合钻井资料对英台大安地区青山口组一段的深水湖底扇特征进行识别。该方法适应于产状比较复杂的地层,而且与传统的时间切片和沿层切片相比更加合理而且更接近于等时沉积界面。结果表明,湖底扇具有敏感的地震响应,在剖面上表现为强的反射波,在地震属性的平面图上,也表现为很强振幅特征。

With application of strata slice technology of seismic sedimentology combined with drilling data to identify deep-water sublacustrine fan on Qingshankou first section of Yingtaidaan area.The approach is for more complex attitude of stratum,but also compared to the traditional time slice and horizontal section,more reasonable and closer to the isochronal sediment interface.The results show that sublacustrine fan is sensitive to seismic response,in the section it appears as a strong reflected wave,in the plan on seismic plan attributes,also showed strong amplitude characteristics.
