利用地震复合属性寻找岩性圈闭
|
摘要
本文着重通针对传统单一地震属性对地层岩性敏感度不高的缺点,难以寻找较复杂岩性圈闭,提出复合属性应用于勘探岩性圈闭。所谓复合属性就是应用数学的方法将多种单一属性进行联合起来得到一种全新的属性。复合属性的敏感度明显优于单一属性,复合属性解释的结果比单一属性解释的结果更好地反应了工区内地层岩性变化区域,更为清楚的突显了沙体尖灭线,为寻找岩性圈闭提供了很好的依据。因此利用地震复合属性是寻找岩性圈闭可靠和有效的方法。
This paper focus on the shortcoming of the traditional single seismic attribute which is of low sensitivity to the formation lithology and Hard to find the complex lithology ctrap , proposes the idea that using the seismic composite attribute in lithologic trap exploration, The so-called seismic composite attribute is to combine several single attributes mathematically to get a brand new single attribute with obvious higher sensitivity than a single attribute,better interpretation result on stratigraphic lithological change area and more clearly highlights the pinchout s line of the sand body. The seismic composite attribute provides a good basis for lithologic traps exploration. So using the seismic composite attribute is a Reliable and effective method in lithologic trap searching.
