Abstract
Frac ture is one of rese rvo ir types that o ften o ccur in ca rbonate, it is im po rtant to identify frac ture and fracture type. In genera ,l the bestm ethod to identify fracture is to use im age logg ing to interpret it d irectly. The image logg ing can identify frac tures and fracture types, but the high logg ing cost is its d isadvan tage especia lly for explo ited o ilfie ld. So the pr im ary w ay to im prove exp lo ited po tential is how to use low logg ing cost m ethod to identify fractures in carbona te reservo ir. In th is paper, we use im age logg ing to ca libra te conventiona l logg ing, then use cross p lo t to estab lish the conventiona l inte rpretation m odule tha t identifies frac tures and fracture types.
