Lithology reservoirs play more and more roles with the developments of the degree and the technology of the exploration in oil exploration. Thus, The new 3D seismic methods in reservoirs description are particularly needed. Attributes analyses and reservoir prediction method, and log constrained inversion method make up a perfect and available technology series. By means of this technology,some of districts such as Xin154, Wang541, Niu871 are found. Examples with the application of seismic methods demonstrate the successful possibility of exploration.
