摘要: 以塔里木盆地库车坳陷和四川盆地西南部犍为地区为例,利用储层岩石学特征对油气运移期次进行了研究.根据储层溶蚀作用和自生粘土矿物的形成期次,结合成岩演化序列成果,确定了库车坳陷中生界储层曾在古近纪末期、新近纪康村末期以及新近纪库车期接受过3期油气充注.对储层成岩演化特点的分析表明,犍为地区下三叠统嘉陵江组储层在中三叠统雷口坡组沉积晚期接受了液态烃充注.上述研究结果与利用地球化学定量(如包裹体)分析手段研究得出的结论普遍吻合,说明运用储层岩石学特征可以确定油气运移期次.

Abstract: The petroleum migration times of Kuche Depression in Tarim Basin and Qianwei area of the southwest Sichuan Basin were determined using petrologic records of oil reservoir.The forming times of reservoir corrosion and diagenetic clay minerals,as well as the diagenetic evolution indicated that the Mesozoic reservoir in Kuche Depression received three charges in the Late Paleogene,Late Kangcun Age of Neogene,and Kuche Age of Neogene.The analysis of the diagenetic evolution of reservoir showed that the reservoir in Lower Triassic Jialingjiang Formation received charges in the Late Leikoupo Age of the Middle Triassic.These results are in good agreement with those solutions obtained by geochemical approaches(e.g.fluid inclusion analysis),which supports that the determination method for oil-gas migration times with reservoir petrology is eligible.

Key words: petroleum migration times, reservoir petrology, corrosion, diagenetic mineral, diagenetic evolution, Kuche Depression, Tarim Basin, Qianwei area, Sichuan Basin
