Abstract: Based on the fracture-vug parameter from electric imaging quantitative processing, conventional well logs and formation testing data as well as crossplot analysis, the quantitative grading standard for various reservoirs is established, and new method of fill-up rate for quantitative evaluation of vuggy reservoir using shale content-areal porosity ratio is proposed. The fluid property discrimination approaches such as gas component analysis, chart analysis, array sonic parameter crossplot, NMR and their suitabilities are studied, by which presents the relationship between logging and seismic attributes of various reservoirs, realizing the integration of microscopic and macroscopic feaures.

Key words: Tarim basin, carbonate rock, fracture-vug quantitativeness, effectiveness, fluid property, borehole-seismic carving
