摘　　要：致密砂岩气已成为当前国内外非常规油气资源勘探开发的重点。通过对准噶尔盆地西部隆起中拐凸起下二叠统佳木河组天然气藏的地质背景、储盖组合与物性特征、气水关系、天然气性质和源—储一体的时空配置关系等研究认为,该气藏位于构造斜坡区(即构造隆起与生烃凹陷之间斜坡带),具有源—储一体的时空配置关系,储气层较为致密,但发育"甜点",气水关系倒置,这些特点为致密砂岩气藏成藏典型特性。结合准噶尔盆地天然气勘探开发现状提出,致密砂岩气将成为该盆地剩余天然气资源中重要的勘探对象,古隆起斜坡带将是致密砂岩气勘探的主要领域。Tight sandstone gas has been one of the most important fields for the unconventional oil/gas exploration,especially in the North America.In recent years,China has found and exploited giant tight sandstone gas reservoirs in the Ordos Basin and Sichuan Basin.It is the first time to discover tight sandstone gas reservoir in the west bulge Zhongguai salient of Junggar Basin.Comprehensive studies have shown that these reservoirs are located in the tectonic slope area between structural high and the hydrocarbon-generation sag.It is characterized by the spatial-temporal configuration relationship of source-reservoir,compact reservoir and＂sweat points＂.These characteristics are typical for compact sandstone gas reservoir.According to the current exploitation situation of the Junggar Basin,compact sandstone gas may be an important exploration subject of remaining natural gas resource and more realistic goal in current unconventional gas and oil resource.The ancient uplift slope belt will be a main exploration area.
