Abstract: On the basis of moldic pore section, cathodoluminescence,enlosure, scanning electron microscope, x-ray diffraction for clay mineral, assay and statistics of bore specimen of over 30 wells in Tian-Chang region of Jin-Hu sag, the reservoir in the region of interest is divided into 3 kinds of patterns and 7 subdivisions. It is thought that main controlled factors of low permeability reservoir are zone of deposition, carbonate content shale content, granul-arity median and so on. Therefore, fracturing and refracturing are main methods of obtaining commercial oil and gas forⅡc andⅢpatterns of reservoir in the East part of Jin-hu sag.

Key words: Jin-hu sag, core analysis, low permeability reservoir, fracturing
