塔里木克拉通盆地改造对油气聚集和保存的控制

显生宙以来塔里木克拉通盆地主要经历了加里东晚期，海西早期，海西末期，印支期和燕山晚期５次主要构造运动的改造，历次构造运动造成的强烈剥蚀区（强烈改造区）弱剥蚀区（弱改造区）和未剥蚀区（未改造区）展布各不相同，从而使盆内油气聚集和保存的时空分布也极不均一。塔中地区主要经历了加里东晚期，海西早期运动的强烈改造，故在这些运动之前形成的油气藏遭受了不同程度的破坏，海西晚期以来，塔中地区相对稳定，有利油气的聚

Control of Basin Reworking on Hydrocarbon Accumulation and Preservation in the Tarim Cratonic Basin, Northwest China

The Tarim cratonic basin mainly suffered the late Caledonian, early Hercynian, terminal Hercynian , Indo - Sinian and late Yanshanian orogenies in the Phanerozoic . The intensely re - worked areas, weakly reworked areas and non-reworked areas produced by various phases of orogenies are inhomogeneously distributed, so that hydrocarbon accumulation and preservation in the basin are changeable in both time and space. Intense reworking during the late Caledonian and early Hercynian orogenies; so oil and gas accumulations formed before these tectonic movements were destroyed to different degrees. Since the late Hercynian, the Tazhong area has been relatively stable, which is favorable for hydrocarbon accumulation and preservation. The Tabei North Tarim area was intensely reworked by the early Hercynian, terminal Hercynian and Indo-Sinian orogenies, and weakly reworked by the late Caledonian orogeny; so the hydrocarbon accumulation, preservation and destruction in the Tabei area are quite complex.
