The sandbodies of fan delta front developed widely in Cretaceous Bashenjiqike Formation in the foreland area of Kuqa depression，which are favorable places for natural gas accumulation. In view of the situation of few drillings and large inter-well spacing in a certain gas field，a typical outcrop，which has the similar geological situation with the target stratum，was chosen to be scanned in multi-faceted and full coverage by the holographic laser scanning technology for acquiring three-dimensional data，and then a three-dimensional digital geological model was built through matching the data with the measured geological information and sampling analysis data by computer simulation technology to reveal the sandbody architecture of fan delta front effectively. The results show that the sandbody architecture types of fan delta front in the study area include three types：incomplete stacked stitching type，side stitching type and isolated type，while the sandbody connectivity are very different owing to the architecture differences. The channel sandbodies are presented as multiple underwater distributary channels stacked vertically and distributed widely，where the physical properties of the middle and lower part are better than that of the bottom and the top and the homogeneous medium sandstone and fine sandstone are the best. A few mouth bars and distal bars are also developed with a negative correlation between the sand thickness and width thickness ratio. The sandstone content of the modeling section is high and there is stable lateral distribution of mudstone interbedded with the sandbodies. The sandbodies are not fully connected with each other and the inner-and interlayer hetero? geneity is strong.
