摘　　要：为了精细描述储层及其非均质性,准确了解剩余油分布及流体流动特征,对储层流动单元进行了分级,提出了渗流域的概念及其划分依据和方法。在临盘油田临2块馆三段次生底水油藏开展了利用沉积微相、测井曲线、夹层、流动系数及流体地球化学特征等资料划分渗流域的研究。将馆三段渗流域划分为A,B,C,D4种类型,剩余油主要集中在C型及CD复合型渗流域。For finely describing the reservoir and its heterogeneity, finding out accurately the distribution of remaining oils and their flowing characteristics,flow unit were divided into different scales,and the author presented the concept of seepage domain and classification criteria. Seepage domain has been classified using the information of sedimentary microfacies, well logs, interlayer distribution, flow coefficient and geochemistry characteristics of fluid. According to these methods,the seepage domain in the third interval of Ng Formation can be divided into 4 types-A,B,C and D, and the remaining oil mainly locates in zones of type C and CD seepage domain.
