Abstract: The Maokou Formation in Jiaotan 1 well field, the central Sichuan Basin, is located near the high-energy beach belt at the platform margin. Owing to the combined effects of paleo-uplift and rifting, it features two phases of beach-facies dolomite with an uplift-and-margin distribution pattern, indicating great exploration potential. However, strong reservoir heterogeneity and large thickness variations impede clear characterization of lithological traps and reservoir units. Accurate prediction of high-quality Maokou reservoirs is therefore critical to exploration and development. Based on the geological characteristics, log responses, and seismic reflection features of Maokou reservoirs, this study proposes a beach-facies-controlled reservoir model. Based on geological data and single-well characteristics, this study defines the vertical distribution of the two-phase beach-facies reservoirs in the Maokou Formation. Paleo-geomorphologic reconstruction is then performed to clarify the coupling between ancient landform and beach reservoirs. Imaging log data and core-derived pore-vug characteristics are used to optimize high-quality reservoir intervals, and seismic forward modeling generates a model for high-quality reservoir identification. Finally, seismic facies, ancient landform, seismic attributes, and seismic inversion are integrated to define the vertical and lateral distribution patterns of high-quality beach reservoirs in the study area. The results show that high-quality reservoirs are mainly developed vertically in the middle and upper parts of the Mao 2 Member and laterally in the paleo-geomorphologic highs of PS6 and PY106 well fields. Separated by tight lithologic barriers and capable of forming independent hydrocarbon accumulations, they cover a total area of approximately 780 km², indicating great exploration potential.
