The three-dimensional distribution parameters of single channel and remaining oil mode about complex glutenite of alluvial fan were confirmed by means of small well spacing and two-pair wells, which were calibrated by core and testing data of well on the basis of modern deposit review and outcrop. The results show that the fanhead subfacies is complex glutenite. The sedimentary source on the vertical orientation are multiples of single channels cutting and overlying, and the single channel has a thickness of 2-6 m and an extension width of 250-750 m. The sedimentary source on the parallel orientation is foreset overlying of many single channels taking on cuneiform and imbricated shape, and the single channel has a thickness of 4-6 m and an extension length of 750-1.750 m. The middle-fan subfacies are characterized by multiple channel lateral overlying, and the single channel has a thickness of 2-4 m and an extension width of 200-1.000 m on the vertical orientation of sedimentary source. The single channel has a thickness of 6-10 m and an extension length of 700-3.250 m on the parallel orientation of sedimentary source. The remaining oil mainly distributes middle-upper location, lateral margin updip piching localization of single channel, mosaic location of different genesis single channel, and contiguous location of different channel for identical genesis.
