摘要通过对志丹油田纸坊北地区长6-长9不同层段储层研究，恢复砂岩储层成岩致密化过程，建立各个层位砂岩孔隙演化规律.依据流体包裹体均一温度、荧光光谱测试分析，确定了研究区长6-长9油层组石油充注期次和时间，查明了该区油藏的成藏史.对成岩-致密-成藏的耦合关系分析结果揭示，研究区长6-长9油藏为"先致密、后成藏"的成岩-成藏特征，为下一步成藏主控因素确定及有利区预测提供理论依据.

Abstract：The diagenetic densification process of sandstone reservoir is restored and pore evolution law of sandstone in each horizon is established through the study of Chang 6-Chang 9 reservoirs in North Zhifang area of Zhidan Oilfield. The oil charging period and time of Chang 6-Chang 9 oil groups, as well as the accumulation history of oil reservoir in the area, are determined on the basis of analysis on homogenization temperature of fluid inclusions and fluorescence spectrum test. The analysis of coupling relationship between diagenesis-densification-accumulation reveals that the Chang 6-Chang 9 reservoirs are characterized by densification before the hydrocarbon accumulation, which provides a theoretical basis for determination of the main controlling factors of accumulation and prediction of favorable areas in the future.

Key words： fluid inclusion compacting history accumulation history Yanchang Formation reservoir Zhidan Oilfield
