摘要	The irregular structures of paleokarst systems are among the major factors resulting in carbonate reservoir heterogeneity, which restricts the further exploration of paleokarst reservoirs. Using multiscale geologicalgeophysical (G&G) data, including thin-section, core-sample and well-log data, the caves, cave fillings andfractures in individual wells in the northern Tahe Oilfield were characterized. Guided by seismic datasets, theinterwell paleokarst structures were interpreted in profile and plane view. The paleokarst system in the studyarea was divided into four vertical zones, and the relative genetic structures were classified in the upper threezones. The epikarst zone includes paleo-canyons, karst towers, dolines, paleo-soils, and fractures, and the waterflows horizontally. The vadose zone includes vadose caves and fractures, and the water flows vertically. Theepiphreatic zone includes chambers, main channels, branch channels and fractures, and the water flows primarily horizontally along the water table. Foreach genetic type, the total hydrocarbon production and monthlyproduction were analyzed. Furthermore, a genetic classification model was built for the paleokarst reservoirs of the study area, which increased our understanding of the structure of the paleokarst system. The results of thestructure classification and production analysis can effectively guide hydrocarbon exploration, and this approachcan be applied to similar paleokarst reservoirs.
