中文摘要	以层序地层学和沉积学为理论指导,综合运用岩芯、钻测井、地震等资料及井-震结合对比分析,对乌夏地区白垩系清水河组与呼图壁河组层序地层及沉积演化特征进行研究,在此基础上分析层序发育控制因素,并建立层序地层演化模式。结果表明:清水河组与呼图壁河组可划分为1个三级层序(KSQ1)和3个体系域,其沉积相类型包括辫状河、辫状河三角洲、曲流河三角洲和湖泊等;构造沉降与古气候为本区层序发育的主要控制因素。层序KSQ1低位体系域时期,研究区地形高差较大,气候炎热干旱,以辫状河相砂砾岩沉积为主,沉积范围局限在乌夏断褶带及其以南地区;水进体系域时期,发生大规模湖侵,沉积范围扩大,主要发育退积式辫状河三角洲、曲流河三角洲;高位体系域时期,转为半干旱气候条件,湖平面下降,发育大规模曲流河三角洲,以三角洲平原沉积为主。
英文摘要	Guided by sequencestratigraphy theories and based on outcrop,drilling, well logging and seismic data,the sequencestratigraphy and sedimentary characters of the Cretaceous Qingshuihe and Hutubihe formations in the Wuxia area of Junggar Basin, Xinjiang, are investigated and a sequencestratigraphic evolution model is proposed. The Qingshuihe and Hutubihe formations represent a third-order sequence (KSQ1) with three system tracts and the braided river, braided river delta, meandering river delta and lacustrine facies. Tectonic subsidence and paleoclimate changes are the main factors controlling sequence development. In the lowstand system tract of sequence KSQ1,there were significant topographic heterogeneity and differences in terrain elevation in the study area, the climate was hot and arid,and the sediments were mainly braided river sandstones and conglomerates that were limited to the southern part of the study area. In the transgressive system tract, there was a massive lake invasion,the sedimentary scope was enlarged, retrogradational braided river delta and meandering river delta were developed. In the highstand system tract,the climate was semiarid,lake level gradually declined, and large-scale meandering river deltas and delta plains were developed.
