Abstract: Vuggy reservoir is one of important types of carbonate reservoirs, its complex and varied features in horizon, scale, filling matter type and filling degree, etc, make the reservoir difficult to be quantitatively discribed using single geophysical model or well logging model.This paper determines the depth of the vuggy carbonate reservoir of Yingshan formation in Tazhong area with the seismic attributes, discribes the vertical scale of vugs, filling matter property and filling degree by imaging logging?conventional logging combination, and evaluates the lateral distribution of vugs by means of the well testing, production test data and the interwell seismic attributes. The studies show that the vuggy carbonate reservoir in this area is characterized and dominated by moniliform seismic reflection, which accounts for 86%,with distribution range of 240 m away from the top Yingshan formation, and the vugs or caves mostly range from 0.5 m to 2 m in height, semifilled and/or fully filled with clay, breccia, etc, with filling rate of 62.8% in average. In lateral, the distribution of vugs is isolated, partly forming fractured?vuggy reservoir with fractures
