摘要： 准噶尔盆地西缘车排子凸起是有利的复式油气聚集区, 近年来在其新近系沙湾组沙二段发现了一批高产岩性油藏, 实现了浅层勘探的重大突破。在研究剖析沙二段油气分布与典型油藏特征的基础上, 重点对沙二段油气主控因素与成藏模式进行了探讨及总结, 提出“湖扩滩坝砂、油气输导体系、侧向封堵条件、古构造脊”是控制油气成藏的4大要 素和“远源、晚期聚集、多因素控藏”的油气成藏模式。指出, 与古湖岸线平行分布的滩坝砂体是今后钻探的重点目标。

Abstract: Chepaizi swell in western margin of Junggar basin is a favorable area with composite hydrocarbon accumulation. In recent years, a number of prolific lithologic reservoirs have been discovered in the Sha-II member of Neogene Shawan formation, representing an important breakthrough in shallow-depth exploration. This paper analyzes the hydrocarbon distribution and typical reservoir characteristics of the Sha-II member, discusses its main factors controlling hydrocarbon accumulation and reservoir pattern, and proposes four main elements to control hydrocarbon accumulation such as lake-enlarged beach bar sands, hydrocarbon conduit system, lateral barrier conditions and paleostructural crest, and the reservoir pattern controlled by multi-factors of distal source and late accumulation. The beach bar sands parallel to the paleo-lake strandline could be the key target for further exploration.

Key words: Junggar basin, Chepaizi field, Neogene, control, factor, reservoir pattern
