采用储层岩相学观察和包裹体显微测温方法,对准噶尔盆地玛湖凹陷斜坡区百口泉组储层流体包裹体进行了详细研究,再结合油气地球化学分析和单井埋藏史恢复了研究区油气充注史。结果表明研究区百口泉组储层经历3期油气充注,2期成藏:以黑色无荧光固体沥青为代表的第Ⅰ期油气充注发生于晚三叠世前,受保存条件限制,早期充注的油气蚀变为固体沥青,并被后期成岩作用改造;第Ⅱ期油气充注发生于早侏罗世,以发黄色荧光的烃类为代表,该期原油充注强度大、范围广,玛东、玛北、玛西和玛南等斜坡区均可见;第Ⅲ期油气充注则发生于早白垩世,以发蓝色荧光的高熟油为代表,同样形成大面积油藏。

According to the observation of characteristics of reservoir petrography and micro-thermometric analysis,the fluid inclusion characteristics and hydrocarbon charging history have been studied comprehensively,combined with hydrocarbon geochemical analysis and burial history reconstruction.The result shows that there are triple hydrocarbon charging and twice petroleum accumulation.The first hydrocarbon charging marked by the bitumen without fluorescence occurred before Late Triassic Epoch and was not collected as the overlying regional cap rock had not been deposited.Thereby,the earliest charged hydrocarbon was altered to bitumen which was subjected to the later diagenetic modification.The second charging represented by the hydrocarbon with yellow fluorescence began from Early Jurassic and the petroleum was finally preserved in most of the Baikouquan reservoir because of the strong intensity and wide range of charging.The third highly mature oil filling represented by the blue fluorescence hydrocarbon happened in Early Cretaceous.
