Hydrocarbon Exploration Signification of Intersalt Sediments in Qianjiang Saline Lake Basin

FANG Zhi xiong

The sequence stratigraphy feature of intersalt sediments is the special rock in Qianjiang saline lake basin, which isn' t simple sediments and has major changes in component and texture with basin area and geologic age. It is very difficult to name it on the basis of their petroleum characteristic. This paper discusses its compo-nent, petrology characteristic and petroleum geologic significance.Its rhythmics on petrochemical element and grain component has an important significance in lake-level relative change. So the comparison and study of the in tersalt nonsandstone rhythm and sequence stratigraphic units was done.By the way, the intersalt nonsandstone is a very eminent assemblage of hydrocarbon reservoir and source rocks, which is a potential good reservoir because of its more secondary porosity. Recently, a very good commercial well was drilled in the rock. sequence.
