On the basis of slice identification and data statistics, this paper analyzed the lithology characteristics, physical properties and controlling factors of standstone of Toutunhe Formation in eastern Fukang slope, Junggar Basin. The result shows that residual primary intergranular pores developed well and are the effective reservoirs, and the reservoir properties are controlled by sedimentary microfacies and diagenesis. Among them, compaction and cementation are the most important factors. Based on the analysis of relationship between reservoirs and sedimentary faceies, the maps of microfacies and sand body thickness were made by making the three submembers of Toutunhe Formation as the mapping unit, and the distribution of standstone reservoir was predicted and evaluated. The favorable reservoir development area was predicted, and five favorable areas with great potential were identified.
