Nm Ⅱ2-4 layers in Qinhuangdao32-6 oilfield are a set of far source sandy braided river reservoirs. According to river configuration classification scheme of Maill，the architecture of the braided river reservoir was analyzed. The genesis，characteristics，identification methods and the superposed pattern of all levels of configuration units were discussed. The fifth level configuration unit is the whole braided river；the fourth level configuration unit consists of three microfacies which are channel，channel bar and floodplain，and four kinds of vertical superposed models were proposed as channelbarfloodplain，channel-channel，channel-bar-channel and channel-bar-floodplain-channel，while three kinds of horizontal contact model were described as channel-beach，channel-floodplain and beach-floodplain. For the third level configuration unit，the channel was divided into bottom energy retention unit，high energy filling unit，accretion unit in the central part and waste low energy filling unit on the top of the channel. The channel bar was divided into vertical accretion body and off silt layer. Three superposed models of the third level configuration unit within the channel are retention-filling-accretion-waste-retention，retention-filling-accretion-retention and retention-filling-retention. The contact relation? ships of the vertical accretion bodies were divided into contact type and isolation type. The controlling factors of the configuration characteristics are terrain conditions，water energy，provenance supply，the ascending-descending of base levels and tectonic movements.
