摘　　要：通过分析准噶尔盆地盆1井西斜坡带下侏罗统三工河组的构造条件、烃源岩条件、储层条件、输导条件、成藏史等方面,结合实际油藏解剖,明确了油气成藏规律;并以此为基础建立了油气成藏模式。最近勘探研究表明,受构造运动影响,斜坡带广泛发育侏罗系层间小断层和少量沟通二叠系油源断层;三工河组储层内部为泛连通,隔夹层规模有限;断裂和泛连通砂体构成三工河组输导要素;受构造运动影响,油气藏类型可分为:原生油气藏、原生破坏型、调整再聚集型油藏。从实钻资料来看:小断裂控藏有利构造位置能够成藏。成藏模式为它源断层垂向运移、砂体侧向运移,低幅构造梁构造圈闭成藏。By the detailed analysis of many aspects of the Lower Jurassic Sangonghe formation of the slope belt of Pen 1 Well West Sag in Junggar Basin, such as the the structure conditions, hydrocarbon conditions, reservoir conditions, transport conditions, history of petroleum accumulation, the rule of oil and gas reservoir is clear. The reservoir formation is established that based on the analysis. The latest research shows that the slope belt which is affected by tectonic movement are extensively developed interlayer small fault and a little source fault which is com- inunicated the permian. The reservoir of Sangonghe formation is panconnected. The scale of the interbed is limit- ed. The transport element is fault and panconnected sandy. The hydrocarbon reservoir which is effected by tectonic movement can divided into three types. They are primary reservoir, destructive reservoir, regulation reservoir. From the well materials, it know that small fault is controlling the oil and gas accumulations, and the favorable structural location is easily forming reservoir. The reservoir formation model is that the fault communicated the source rock, the oil vertically migrate following the fault, and lateral migrate in sandy, and accumulated in structural trap in low amplitude structure beam.
