摘要
塔里木盆地是一个长期发育的巨型克拉通复合型含油气盆地。其形成演化历经前震旦纪基底形成旋回、震旦纪—早二叠世克拉通盆地发展旋回和晚二叠世—新第三纪前陆与陆内盆地发展旋回。海西晚期和喜马拉雅期是主要生油气期和油气聚集成藏期。
Tarim is a huge hydrocarbon-bearing basin that underwent three developmentalcycles:1.Presinian basement-forming cycle;2.Sinian-Early Permian cratonic basincycle;3.Late Permian-Neogene foreland and inland basin cycle.The Manggar Depressionformed in Caledonian is the main hydrocarbon-generating depression;the North Tarimuplift,the Central uplift and the slopes are the directional area for hydrocarbon migrationand accumulation;the Ackule,Yakela-Shaxi nose-type uplifts formed in early Hercyniancontrolled the distribution of oil provinces.The important tectonic movement in late Her-cynian caused the complete secession of the sea water from the basin,and ended the deve-lopment cycle of the cratonic basin.Hercynian was the main period for the formation oflocal structures,the fault activity,and the generation and accumulation of hydrocar-bon.Himalayan was the principal stage for hydrocarbon generation and accumulation af-ter Hercynian,Triassic-Jurassic source rocks were buried deeply and matured,Cambrian-Ordovician and Permo-Carboniferous formations were buried to generate hydrocarbonagain in this period.
