【摘要】 基于大量地质与地震资料,分析总结了准噶尔盆地周缘隆起带地质结构及地层充填特征,研究了隆起带圈闭、烃源岩及输导体系空间配置关系后指出,准噶尔盆地周缘隆起带发育着持续隆升、先拗后隆、隆拗反复等3种垂向演化类型,对应形成3种地质结构。持续隆升型隆起具有"旁源侧圈"空间配置关系,先拗后隆型、隆拗反复型隆起具有"下源上圈"、"圈源同位"、"旁源侧圈"等空间配置关系,不同的圈源配置关系有不同的输导体系。受不同地质结构控制下圈团、烃源岩、输导体系发育特点及其空间配置关系的影响,盆地周缘隆起带具有3种油气成藏模式。盆地周缘隆起带的车排子南部、哈山地区—红旗坝、木垒等地区资源潜力较大,应是今后勘探的有利方向。更多还原

【Abstract】 Based on the geological data and seismic information, the geological structures and fill characteristics in peripheral uplift beltsof Junggar basin were analyzed and summarized, and the space allocations of traps, source rocks and transport systems were studied. It ispointed out that three vertical evolution types of continuous uplifting, depression followed by uplifting and repeated uplifting and depres-sion occur with corresponding three geological structures. The continuous uplifting type is characterized by the space allocation of"trap be-side source rock", the others by"trap on source rock","trap together with source rock"and"trap beside source rock", and the differenttrap-source rock allocations are of different transport systems. Under the effects of the development characteristics of trap, source rock,transport system and their space allocations controlled by different geological structures, the peripheral uplift belts have three types of hy-drocarbon accumulation patterns. It is concluded that the southern Chepaizi, Hala’alat-Hongqiba and Mulei areas in the peripheral upliftbelts of Junggar basin could be the favorable targets for petroleum exploration in the future.更多还原
