Abstract: Through technologies such as karst paleogeomorphology restoration, dip angle constraint enhanced coherence, facies-controlled karst seismic inversion, and nonlinear gamma simulation, the distribution patterns of facies-controlled karst anomalies and effective reservoirs of Permian Maokou Formation in Yuanba area of Sichuan Basin were studied. The results show that:(1) The Permian Maokou Formation in Yuanba area can be vertically divided into three karst zones:surface weathered crust, vertical seepage zone, and horizontal subsurface flow zone. The facies-controlled karst reservoirs of the third member of Maokou Formation are jointly controlled by shallow shoal facies and karstification, and the reservoirs can be divided into pore-cavity type and semi-filled karst cave type.(2) The karst residual hills have relatively high landform, serving as a water supply area for karstification, and are favorable for the development of facies-controlled karst. The karst plains have relatively low landform and are catchment areas for karstification.(3) The enhanced coherence technique with dip angle constraint can qualitatively describe the favorable zones of facies-controlled karst development within the residual hills. This type of reservoir in the study area is mainly distributed in high areas of ancient landforms and is distributed in a northwest direction.(4) The prediction method of facies-controlled karst reservoirs can relatively accurately predict the distribution range of effective karst reservoirs. The karst reservoirs in the ridge and peak cluster zones in the study area are the most developed, with a maximum thickness of 28 m.

Key words: dip angle constraint enhanced coherence, facies-controlled karst, restoration of ancient landform, karst seismic characterization, karst reservoir prediction, Maokou Formation, Permian, Yuanba area, Sichuan Basin
