摘要
为认识三角洲成因机制、分类描述及其与油气生成聚集的关系,以准噶尔盆地白家海地区侏罗系地层为例,在中期基准面旋回框架内采用岩心观察描述、测井相分析方法,以沉积体系域为成图单元,从古地理背景、构造背景、形态特征、沉积构造发育特征、岩性及相组合等方面对侏罗系时期发育的不同类型三角洲沉积体系进行分类描述与成因机制研究.结果表明:3种类型三角洲沉积体系具有很大差异性,并决定其发育砂体类型与分布的各自特征.
In order to recognize the forming mechanism and category description of delta and the relation between delta and petroleum formation and accumulation,the Jurassic of Baijiahai area in Junngar Basin was chosen as an object of study.In the framework of mid-term base-level cycle,by means of core observation and electrofacies,using sedimentary system tract as mapping unit,under the background of paleogeography and structure,morphology characterisc,sedimentary structure,lithology and facies association,different kinds of deltas of Jurassic were described thoroughly and the formation mechanism were analyzed.The results are of three different kinds of delta and these differences determined sand types and distribution characteristic of each kind.
