This paper introduces several main methods of fractured reservoir characterization and modeling, and summarizes their
essential advantages and disadvantages. The main methods for fracture characterization include field study, core and well logging,
seismic prediction, dynamic response analysis, mechanical analysis, and rock mechanical analysis. And fracture modeling is conducted
mainly with by DFN (discrete fracture network) and equivalent continuum modeling. This paper reviews the application of fractal theory
to outcrop fracture analysis of volcanic rocks, the application of digital core technique to micro fracture characterization, several most
recent geophysical and mechanical fracture characterization and prediction methods, the impact of dynamic fracture on reservoir
development, fracture stratigraphy theory proposed abroad lately, fracture characterization in unconventional reservoir, and finally the
above two fractured reservoir modeling methods. On the basis of all above, challenges for fracture characterization and modeling and
future research in this field are pointed out.
