摘要: 塔里木盆地巴楚—麦盖提地区有效烃源岩为寒武系—中下奥陶统和石炭系,巴楚隆起和麦盖提斜坡2套烃源岩演化历史有较大的差异。该区油气运移疏导系统主要为储层孔隙和裂缝系统、断裂系统与不整合面;主要有3期成藏,即加里东晚期—海西早期、海西晚期和喜马拉雅期。其中加里东晚期—海西早期油藏多被破坏;海西晚期油藏保存有好有差,后期又有调整;喜马拉雅期主要为气藏形成与古油藏调整期。根据主要成藏时期及成藏条件的配置关系、源岩及储层的关系,认为巴楚—麦盖提地区大致存在4种成藏模式:早期成藏他生、早期成藏次生、早期成藏—破坏—晚期成藏和晚期成藏。Abstract: There are 2 sequences of source rocks including the Cambrian-Middle-Lower Ordovician and the Carboniferous in the Bachu-Maigaiti area of the Tarim Basin.The source rock evolution history in the Bachu Uplift is different from which in the Maigaiti Slope.The hydrocarbon migration systems include reservoir fracture,fault and unformity.The hydrocarbon accumulation in the area can be divided into 3 periods such as the late Caledonian-early Hercynian,the late Hercynian and the Himalayan.Reservoirs were destructed in the late caledonian-early Hercynian,destructed or persered in the late Hercynian and generated or adjusted again in the Himalayan.Acorrding to major hydrocarbon accumulation as well as source rocks and reservoirs,there are 4 types of hydrocarbon accumulation models in the area: a)the early hydrocarbon accumulation;b)the secondary early hydrocarbon accumulation;c)the early hydrocarbon accumulation-destruction-late accumulation again;d)the late hydrocarbon accumulation.
