Abstract: Junggar basin is rich in hydrocarbon resources, low degree of prospecting and high potential for exploration. Based on its prospecting status and efforts, this paper makes the analysis and discussion of the control factors for petroleum accumulation and targets for further exploration. It is concluded that non-structural reservoirs will be ma jor ty pes of prospecting; the slope belts with high swells are of conditions for forming large-scale stratigraphic reservoirs; in complex piedmont thrust nappe there are many targets and high potentials for exploration; Jundong (easterm Junggar) area and around W ulungu depression are not "dead areas of hydrocarbon generation", they should be regarded as fav orable backup positions of prospecting.

Key words: Jungar basin, hydrocarbon resource, exploration, target
