Abstract：The fault can not only be as migration channel of petroleum,but also can seal petroleum.The analysis and the determination of fault-closed area can directly divide the scope of petroleum formed by sealing in a complicated fault-block zone which is near oit sources and has abundant content of sandstone.The sealing patterns of the areas mainly are lithologic seals on both side of fault.The ideal method for analysis of lithologic juxtaposition is determination of lighologic juxtaposition of fault plane by drilling data on the both sides of fault.But in practice,due to lack of drilling data,the work is difficult to carry out.Comparing different well-log constrained seismic inversion by analysis,we found inversion by geologic statistics to be the method that the result of inversion is reliable,which can obtain a rather ideal lithologic section,from which we can study the lithologic juxtaposition relation of fault plane and first applied it to study the sealing analysis of Minfeng fault zone.
