摘　　要：为了对沙洼沟区延9沉积微相进行研究,通过岩心精细观察、沉积构造、粒度曲线特征、测井曲线组合特征等对延9油层组沉积微相进行了研究。结果表明其沉积相类型为曲流河,发育边滩沉积微相,自北而南发育2条大的河道。The sedimentary microfacies of Yan9formation in Shawagou area were described by use of core fine observation,sedimentary structure,grain size curve characteristics and combination characteristics of logging curves.The results show that thesedimentary facies are meandering river,in which the microfacies of the marginal beach are developed,and2large rivers aredeveloped from the north to the south.
