准噶尔盆地腹部地区侏罗系沉积体系展布
|
摘要
利用地震、测井、岩心资料,根据沉积构造、相序、岩性剖面结构、砂体厚度、含砂率变化确定了准噶尔盆地与腹部地区侏罗系沉积体系及分布.结果表明:该区堆积了近4000m厚的浅水辫状三角洲相粗粒砂砾岩与深水湖泊相泥岩沉积,以广泛发育的辫状三角洲沉积体系为特征.西北缘、西缘和东侧发育3大物源区,相应地形成3支砂体.早侏罗世具"三分"或"二分"沉积体系分布格局,中侏罗世西山窑组沉积时期是重要转折点,此后水深总体变浅,中晚侏罗世继承了"二分"格局,但出现大面积剥蚀区.
Based on the seismic,well-loggings and cores,Jurassic deposition systems and distributions were determined in Junggar basin and its hinterland areas,by sedimentary structures,facies,lithological textures of profiles,thicknesses of sandstone bodies and ratios of sandstones to strata. It turned out that the mudstones of deep-water lake and the coarse-grained gravelstones and sandstones of shallow-water braided deltas were accumulated with the depositions characterized by the braided deltas and thick 4000m. Studies displays three main provenances of the eastern,western and northwestern Junggar basin developed here,three main branches of sand-bodies correspondingly were produced; during Early Jurassic,there was a depositional system distribution framework of three-parts or two-parts; the Middle to Late Jurassic had inherited that of two-parts but there occurred extensive denudation zones,because the depositional phase of Middle Jurassic Xishayiao Formation was a turning point,and hereafter water depths became shallower and shallower.
