Abstract: Fractured-vuggy carbonate reservoir space are complex，showing very strong heterogeneous and multi-scale feature.
Despite the fact that certain well water drive characteristic curves presen sandstone reservoir characteristics or single straight
segment characteristics，much of the rest well water drive characteristic curves are step-like curve with segments of straight
line or irregular features，so it is not justified to apply water drive characteristic curve into them without selection. In this
paper，more than 50 water drive characteristic curves at home and abroad are screened，and water drive characteristic curve for
Sangnan Western is selected for application. The analysis results show that the correlation of practical data and applications is
the key consideration when applying water drive characteristic curve to fractured-vuggy carbonate reservoir. In order to further
perfect the application of water drive characteristic curve of fractured-vuggy carbonate reservoir，the relevant matters of water
drive characteristic curve application for fractured-vuggy carbonate reservoir are presented，too.

Key words: fractured-vuggy carbonate reservoir, water drive characteristic curve, step-like curve with segments of straightline, water drive regulation, production characteristic
