摘要
This paper tried to explore its genesis and patterns. The authors made a detailed analysis of sedimentary facies and dissection of section structure of the reservoir sand body, and found that the study area of Xujiahe is composed mainly of single underwater distributary channel sand, single-mouth bar sand, lake sand bar sand, shallow lake sand bar sand, superimposed distributary channel sand, superimposed mouth bar sand, and combination type of underwater distributary channel and mouth bar. The results show that in the study area of Xujiahe, the most favorable places for the reservoir development are the middle-lower reaches of the river and the middle and upper parts of the mouth bar.
