Abstract: The authors found the indicative characteristics of paleokarst reservoir in Yichuan-Huanglong area in the southeastern Ordos basin, after a comprehensive analysis combining with seismic, well logging, and core data. The core data demonstrate that the reservoir rocks are mainly gypsum-bearing dolomite and secondary limestone; the reservoir spaces are vugs in dolomite, relatively isolate caves,and fractures; the reservoirs are tight,the porosity varies from 0.30% to 11.54%,with an average of 3.90%, and the permeability varies from 0.002×10-3 μm2 to 15.450×10-3 μm2,with an average of 0.710×10-3 μm2. Reservoir quality is affected by bedded karstification. The comprehensive analysis was further conducted based on paleo-geomorphology, depositional facies,and fractures. The results suggest that the western area of the Ordovician platform in Yichuan is a favorable target for exploration and development due to its high position in the paleo structure and bedded karstification in the reservoir.

Key words: Ordos basin, Ordovician, Majiagou Formation, bedded karstification reservoir
