摘　　要：通过对32口密闭取心检查井低渗透油层逐层解剖和分析,认为在目前井网条件下低渗透油层水洗动用状况差,分析了油层的物性、厚度、分层系数、含油性、连通类型、井点位置、注采井距等因素对低渗透油层水洗动用状况的影响,为今后低渗透油层的开发利用提供了依据。Based on layered dissection of low permeability oil layers from 32 pressure coring inspection wells and succedent analysis, it is believed that under current well pattern the flushed producing performance of low permeability oil layers is poor. The effect of some factors, such as physical properties of oil layers, thickness, individual layer coefficient, oil-bearing features, connectivity types, well sites, producer-injector distance, etc., on flushed producing performance of low permeability oil layers are analyzed. It will be useful for latter development of low permeability oil layers.
