摘　　要：准噶尔盆地中部S区块是老油盆的新区块,其重点勘探层位西山窑组,已有工业性油气产出.综合分析了沉积微相与油气勘探的关系,采用"点-线-面"的立体空间研究思路,作出了三维的微相划分和相关的4种有利储层类型划分.中S区西山窑组沉积特征是,整体处于水退的环境中,兼有短期的水进,其中Y1井区主要经历了浅湖-湖沼-辫状河三角洲前缘-滨湖相,最有利微相是2砂组的辫状河三角洲前缘水下分流河道.The Block S in Central Junggar Basin are a new block in the maturing field now, whose exploring layer focus on Xishanyao Formation, and has yielded commercial oil and gas. This article analyzed synthetically the relationship between sedimentary microfacies and oil-gas exploration, with stereo clue of ＂point-line-face＂, and made the classification of three-dimensional microfacies and distinguished 4 types of favorable reservoir. It is confirmed that the sedimentary character of Xishanyao Formation of Block S is that it is entirely in a transgressive environment, with a short period of regression. In District of YI Well, there had come through： shallow lake-lake swamp-braided delta-front- littoral lake. The most favorable microfacies are the subsequeous distributary channel of braided delta-front of 2 Sand Bed.
