根據(jù)穩(wěn)定滲流過程中質(zhì)量流量的連續(xù)性特征 ,對精細(xì)油藏描述數(shù)據(jù)的粗化處理方法進(jìn)行了研究。結(jié)果表明 ,串聯(lián)網(wǎng)格平均滲透率為細(xì)網(wǎng)格滲透率的調(diào)和平均 ;粗網(wǎng)格的平均滲透率與所設(shè)定的流入端與流出端的壓差大小無關(guān) ,只與細(xì)網(wǎng)格的滲透率和幾何尺寸有關(guān) ;某一方向上滲透率的粗化結(jié)果與另外兩個方向上滲透率分布有關(guān)。油藏數(shù)值模擬結(jié)果表明 ,粗化后的地質(zhì)模型與原模型是等效的 On the basis of fluid mass rate equivalent in stead state flow, an up-scaling technique for analyzing data of fine reservoir description was proposed. The analysis results show that the average permeability of grids in series connection can be calculated harmonically, and the coarse grid permeability has something to do with permeability of fine grids, and nothing to do with the given pressure difference between inflow end and discharge end. The up-scaled grid permeability will be affected by fine grid perm...
