塔里木盆地是多旋回叠合盆地,主要烃源岩为奥陶系和寒武系,其古生界盆地经历过海西早期、海西晚期和燕山晚期等三期主要构造运动,现今具典型的残余盆地性质。开发了三维油气盆地定量描述和动态模拟软件系统,对塔里木盆地进行了全面研究。三期构造运动所剥蚀的(古生界)排油气损失量之和约占累积排油气量的12%左右。其中以海西早期剥蚀的排油气损失量最大,达263×10~8t;奥陶系排油气损失最严重,其次为寒武系。塔里木盆地的油气资源潜量仍十分巨大,油127×10~8t,气68×10~8t 油当量。含四个石油资源潜量富集区,按强度依次为满加尔蚴陷、唐古巴斯坳陷、阿瓦提坳陷和巴楚隆起;天然气资源潜量富集区三个,依次为满加尔坳陷、唐古巴斯坳陷和阿瓦提坳陷。且末北部有一个从石炭纪以来长期继承性发育的鼻状隆起带,是满加尔坳陷的油气运移指向地区,有可能形成大型复合油气田。
The Tarim Basin is a multi-cycle superimposed basin. The main hydrocarbon source rocks are Ordovician and Cambrian. The Paleozoic basin experienced three major tectonic movements in the early Hercynian, late Hercynian and late Yanshanian periods. Nowadays, there are typical residuals Basin nature. The quantitative description and dynamic simulation software system of 3D oil and gas basin was developed, and the Tarim Basin was fully studied. The amount of oil and gas losses eroded by the Tertiary tectonic movement accounted for about 12% of the accumulated oil and gas emissions. Among them, the loss of oil and gas in the early Hercynian erosion was the largest, reaching 263 × 10 ~ 8t. The loss of oil and gas in the Ordovician was the most serious, followed by the Cambrian. The potential of the Tarim Basin oil and gas resources is still huge, oil 127 × 10 ~ 8t, gas 68 × 10 ~ 8t oil equivalent. There are four oil-rich areas with rich mineral resources, followed by Manjar larvae, Tanggoubas Depression, Awati Depression and Bachu uplift in intensity order. There are three areas with rich natural gas resources, followed by Manjar Depression, Tanguebasasian depression and Awati Depression. In the northern part of the northern part, there is a nose-like uplift belt developed from the Carboniferous to a long-term inheritance. It is the area where oil and gas migrate to the Manjiaer Depression, and it is possible to form a large composite oil and gas field.
