Conventional log technology is difficult to evaluate correctly some complex reservoirs which are characterized with complicated pore space,special lithology and inhomogeneous layers such as conglomerate reservoir,carbonate reservoir,igneous reservoir and so on,it is necessary to resort to some high-technology logs.As a base of new theory,nuclear magnetic resonance(NMR) log can provide accurate porosity which is little dependent of lithology,so it can be used for reservoirs identifying.Characterizing porosity structure,T2 distribution of NMR can be used to identify valid fractures and vugs and a series of rules are summarized as a table.Furthermore,at special conditions without water in reservoirs,the ratio value of movable fluid volume and total porosity maybe regard as oil saturation.With these methods,characterization of fractures and vugs are described in Chegu 20 Buried-Hill carbonate reservoirs,and oil saturation of carbonate reservoirs of Chengbei zone is calculated,which is profound for accurate reserves.
