Seismic Compound Attribute Applied to Lithologic Reservoir Prediction

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.
