Abstract: Junggar basin is an inland basin with a roughly triangular shape. Since the formation of the basin from the Late Carboniferous, sedimentary formation developed in Upper Carboniferous to Quaternary.The exploration area in the hinterland of Junggar basin is huge. The prediction of favorable area of exploration activity in the next step becomes a crucial question. Multi-factor matching model for hydrocarbon accumulation is an effective and reliable method to predict the favorable distribution area of hydrocarbon reservoir, in this paper, we will use the multi-factor matching model for hydrocarbon accumulation, we set up a quantitative mathematical model of controlling reservoir of each main controlling factor and weighted average of four single factor controlled reservoir probability to get the functional factors integrated control of possession probability index and the favorable accumulation area of the Jurassic reservoir in Junggar basin is predicted.
