Abstract：Erlian Basin is a middle-scale oilfiled of China. Our work in the basin is as follows：merging and process gravity and magnetic data acquired in the basin, analyzing the geological implications of the data, and finally predicting Upper Paleozoic structures together with available seismic data. The comprehensive study concludes that Upper Paleozoic formations are dominantly controlled by big deep faults in the basin. In the north of the Xilam-ulun-River fautt, the residual Upper Paleozoic formations have the Dig thickness. There are two thickness centers, i. e. Eriian-Suyouqi Zone and Xwuqi-Dongwuqi Zone. The maximum thickness of the former is about 3000 m, and the maximum thickness of the later is about 6300 m. Both of them have not only big thickness but also a wide coverage, and are considered as future potential targets.
