摘要： 准噶尔盆地是不同性质的原型盆地相叠加的复合型盆地, 地层油气藏极其发育。该区主要发育地层超覆、地层削截不整合、下切河道砂体及基岩潜山等4 种地层油气藏, 具有类型多、规模大、发育层系多、时空展布受古地貌控制的特点。多套优质烃源岩、不整合输导能力、优质储集相带及多期次构造运动是准噶尔盆地地层油气藏主控因素。该区地层油气藏可以划分为近源自生、远源混生2 种成藏模式。盆地周缘隆起区及盆内隆起区是寻找大型地层油气藏的2个有利方向。

Abstract: Junggar basin is a composite basin superimposed by different kinds of proto-type basins with well developed stratigraphic reservoirs. Four types of stratigraphic reservoirs mainly exist in this area such as stratigraphic overlap reservoir, truncated stratipraphic unconformity reservoir, downcutting channel sand reservoir and basement buried hill reservoir, which are characterized by various types, large scale, multi-strata and paleogeomorphology-controlled time-space distribution. The major controlling factors for these stratigraphic reservoirs in this basin include multiple high-quality source rocks, unconformity transporting capacity, high quality reservoir belts and multistage tectonic movements. The stratigraphic reservoirs are classified into two reservoir models. One is "near source and selfgeneration" and the other is "far source and mixed genration". It is concluded that the uplifts in inner and surrounding Junggar basin are favorable exploration targets to find out large-scale stratigraphic reservoirs.
