摘　　要：引进定量颗粒荧光分析技术对准噶尔盆地哈山地区侏罗系-白垩系古油藏和残余油藏进行定量荧光QGF和QGF-E分析,该技术在浅部储层研究中的应用结果表明,准噶尔盆地哈山地区侏罗系-白垩系的颗粒荧光指数和QGF-E值呈现由西向东逐渐降低的趋势,且二者强度呈正相关,越临近油源的取样井,荧光现象越明显,含油丰度越好。研究层位疏导性能强,浅层的反冲断裂和断展褶皱导致油气轻烃组分的散失,垂向上油气具有从深部向浅部运移的趋势,且浅部现今油藏烃类组分更重,含油丰度更高;侧向上整体流体势呈现由西向东逐渐降低的趋势,逆冲断层自西向东由陡变缓,烃类流体荧光强度、密度及粘度也随之呈现逐渐减小趋势。通过该应用研究可知,定量颗粒荧光分析技术是检验含油层段的有效手段,对于揭示研究区域油气运移路径,研究油气成藏特征具有重要意义。Quantitative grain fluorescence analysis technique was introduced to conduct QGF and QGF⁃E analyses of Jurassic⁃Cretaceous paleo⁃reservoirs and residual reservoirs in Hashan area of Junggar Basin.Application of the technique in shallow reservoir study shows that the QGF Index and QGF⁃E values of Jurassic⁃Cretaceous in Hashan area of Junggar Basin gradually decrease from west to east,and their intensities are positively correlated.The closer the sampling wells to oil sources,the more obvious the fluorescence phenomenon and the better the oil abundance.The study horizon has strong dredging performance,shallow recoil faults and fault⁃spreading folds lead to the loss of light hydrocarbon components of oil and gas,vertical oil and gas have a trend of migration from deep to shallow,the hydrocarbon components of shallow reservoirs are heavier and the oil abundance is higher.The lateral fluid potential decreases gradually from west to east and the thrust fault changes from steep to flat from west to east.The fluorescence intensity,density and viscosity of hydrocarbon fluids also decrease gradually.Through this application study,it can be seen that quantitative grain fluorescence analysis technique is an effective means to test oil⁃bearing intervals,and it is of great significance to reveal the migration path of oil and gas in the study area and study the characteristics of oil and gas accumulation.
