Abstract：Shale oil resources have great potential in China. Development of fractures is an important factor affecting shale oil production. Taking the shale reservoir of the Fengcheng Formation in Mahu sag of the Junggar Basin as the research object,the development characteristics of fractures in the study area are summarized through core observation,thin section identification,conventional and imaging logging methods. The comprehensive logging identification method of “conventional+imaging+core” is further proposed,and the logging comprehensive identification chart of typical fracture development types is established. The results show that the natural fractures in Mahu area intensively developed in the P1f3, less in the P1f1, and almost none in the middle of the P1f2. Fractures mainly developed in felsic shale,dolomitic shale, and mixed shale,mainly high-angle structural fractures and low-angle diagenetic fractures,with high opening degree. A few fractures are filled with carbonate minerals,and the strike is mainly NW-SE. Based on the quantitative calculation results of fracture parameters,combined with lithology,mineral composition and in-situ stress,the effectiveness of reservoir fractures is analyzed. The study shows that the high-angle unfilled fracture development section with high content of brittle mineral components and strike parallel to the current horizontal maximum principal stress has an obvious control effect on reservoir effectiveness,which is consistent with the liquid production data. The comprehensive evaluation method of fracture logging has remarkable effect,and can provide method support for fracture identification and effectiveness evaluation of shale reservoir.
