is a hot spot for geologists and geologists in recent years.. When gas condensate oil content is equal to or greater than 50g/m, gasoline generally greater than 800m -1000m, called condensate gas reservoir. Condensate gas reservoir phase is more complex, in the original formation condition, natural gas and condensate oil in a single state of the gas phase, and retrograde condensate rule compliance within a certain pressure range, it is a special type that different from the reservoir and gas reservoir.This type is mainly distributed in Western China including Tuha basin and Tarim Basin, it is also found in Bohai Bay Basin and Dongpu depression in the eastern part of the depression.In recent years, with the continuous deepening of exploration of Hailaer basin, condensate gas reservoir was found in second segment of Nantun formationof well He10, showing good prospects for exploration. In this paper, reservoir forming conditions were investigated, the forming model of condensate gas reservoirs was establishment, and favorable exploration area were predicted, the results have important guiding significance.
