摘要： 乌夏地区南北分3 个带，东西分3 个变形区，共划分为9 个构造单元，发育9 种构造岩相带，三大沉积体系。不同的构造带发育不同的沉积体系，生长断层造成断层两侧同期地层沉积厚度与沉积体系的明显差异，断层的走向控制沉积体系的展布方向，阶梯式逆冲断层可形成多级断崖扇。乌尔禾背斜扇三角洲前缘（冲积扇扇中）、乌夏—卡拉麦里冲断区扇三角洲平原（冲积扇扇根）及夏红断褶区扇三角洲平原（冲积扇扇根）构造岩相带是油气聚集的有利区。

Abstract: Wuerhe-Xiazijie area is divided into nine structural units, and has nine sedimentary facies types and three sedimentary systems. The different structural zones allowed to developing different sedimentary systems. The growth fault caused the differences in sedimentary thickness of isochron strata and in sedimentary system in two sides of the fault. The fault's strike controlled the distribution directions of the sedimentary systems, and the step thrust faults formed multiple steep fan-delta. Wuerhe anticline fan-delta front (middle alluvial fan), Wuerhe-Xiazijie-Karameli thrust belt fan-delta plain (root alluvial fan), Xiazijie-Hongqiba bruchfalten zone fan-delta plain (root alluvial fan) tectonic-lithofacies zones are favorable locations for hydrocarbon accumulation.

Key words: Junggar basin, Wuerhe, Xiazijie, structural system, tectonic-lithofacies zone, hydrocarbon accumulation
