| 摘 要： | 综合油气地球化学、流体包裹体和构造演化资料，对塔里木盆地顺北地区奥陶系不同断裂带油气性质差异性、成藏期次及油气充注过程进行研究。地球化学分析表明，顺北地区不同断裂带油气物性和成熟度存在差异，由西向东从7号断裂带向1号断裂带原油密度变小，西部的7号带和5号带北段油气成熟度低，5号带南段和1号带油气成熟度高。包裹体分析结果表明，顺北地区奥陶系油气藏存在加里东晚期、海西晚期及喜马拉雅期多期油气充注过程。自西向东不同断裂带上主成藏期存在差异，西部的7号及5号断裂带油气成藏期为加里东晚期和海西晚期，东部的顺北1号断裂带多了一个晚期油气成藏即喜马拉雅期成藏。顺北地区多期油气充注成藏是导致该区油气成熟度变化的主要原因。研究区奥陶系成藏期古构造对断裂带的油气充注具有控制作用。加里东晚期，研究区走滑断裂带构造均处于充注有利区；海西晚期，顺北11号断裂带及其以西地区充注来自东部满加尔的油气概率较低。喜马拉雅期，仅顺北1号断裂带及其以东获得高熟油气充注。

| Abstract: | The filling history and accumulation process of oil and gas reservoirs were studied by using the data of oil and gas geochemistry, fluid inclusions,and tectonic evolution. There are three periods of hydrocarbon accumulation in the Shuntuoguole area of the Tarim basin, which were in the Late Caledonian, Late Hercynian, and Himalayan. There are differences in the main reservoir forming periods between the different fault zones. The main hydrocarbon accumulation period in No.7 and No.5 fault zones in the west was in the Late Hercynian. In the Eastern Shunbei No.1 fault zone, not only the Late Hercynian hydrocarbon accumulation, but also Himalayan hydrocarbon filling occurred. The reasons for the change of physical properties of oil and gas are multi-stage oil and gas filling and Ordovician paleotectonic evolution. The oil and gas filling periods of the fault zone are controlled by the paleostructure. In the Late Caledonian period, the strike slip fault zone of the study area was located in the favorable area for charging of the oil and gas generated by the source rocks of Manjar depression in the eastern basin; in the Late Hercynian period, the charging opportunity with oil & gas from the Manjiaer depression in the west of the fault No.11 was low; In the Himalayan period, only the Shunbei fault No. 1 structural belt and its east obtained high-mature oil and gas filling. |
