摘要： 在分析准噶尔盆地南缘霍尔果斯构造地质特征的基础上,重点解剖了构造的样式、油气成藏条件及异常高压等特点。霍尔果斯构造展现了深浅两种构造样式，侏罗系和白垩系是主要的烃源岩层,主要储集层为古近系紫泥泉子组薄层细砂岩、粉砂岩,单层厚度不大,多为2~8m,最大可达12m,沉积相主要为辫状河三角洲前缘亚相。在成藏特征分析的基础上,提出了南缘异常高压条件下的复杂构造油气成藏模式。

Abstract: The geologic feature of Huoerguos structure in southern margin of Junggar basin is analyzed by focusing on its structural style, hydrocarbon accumulation condition and abnormal high pressure. Study shows that there exist deep and shallow structural styles in Huoerguos structure. Jurassic and Cretaceous are its principal source rocks. Ziniquanz formation of Paleogene is its main reservoir rock featuring thin fine sandstone and siltstone and averaging 2~8 m (12 m in maxmum) of single layer thick ness. Braided delta front subfacies is its sedimentary facies. The pressure is divided into two pressure system. The complex structure and hydrocarbon accumulation model under the condition of abnormal high pressure in southern margin of Junggar basin is proposed based on these analyses.

Key words: Junggar basin, structural reservoir, , abnormal high pressure, hydrocarbon accumulation model
