摘要: 海西运动期是塔里木盆地构造演化中的一次重要变革期,定型于该时期的古隆起周缘紧邻生烃中心,是油气运移的长期指向区;断裂和岩溶作用的发育为油气的运聚提供了良好通道及储集空间。而台盆区后期构造运动的稳定及石炭系区域泥岩盖层的叠合与碳酸盐岩缝洞系统构成有效储盖体系,匹配于中下寒武统烃源岩的海西运动期生油高峰,有利于台盆区大油气田的形成与保存。根据台盆区“古隆起控油、斜坡带富集”的油气分布规律,指出塔中、轮南、英买力及巴楚古隆起是台盆区加强黑油勘探的有利领域。

Abstract: The Hercynian movement is a significant event for tectonic evolution in Tarim basin. The paleohighs adjacent the source center in this period should be long-term objective area for hydrocarbon migration; the existing faults and karstification provided channels and pore volumes for petroleum migration. The relative stability of late tectonic movement and the superposition of regional shale cap rocks constituted effective reservoir-cap rock system with carbonate cavities, which just matched the Hercynian oil-generating peak of Middle- Lower Cambrian source rocks, being favorable to the formation and preservation of large oil-gas fields in this area. According to petroleum distribution rule of "oils controlled by paleohighs and enriched by slope belt", it is concluded that Tazhong, Lunnan, Yingmaili and Bachu paleohighs or uplifts are most favorable domains for further petroleum exploration.

Key words: Tarim basin, Hercynian movement, paleohigh, uplift, marine hydrocarbon accumulation
