摘　　要：应用传统的实际开发资料计算法、数值模拟法对油田合理采油速度进行预测，并通过国内25个低渗透油田区块的资料，回归出采油速度与地层流动系数以及井网密度的关系，绘制了预测采油速度图版。运用以上方法，对焉耆盆地宝北区块合理采油速度的比较，得出在目前井网条件下的宝北区块Ⅱ油组和Ⅲ1小层的合理采油速度分别为2％和2．5％．： By using traditional calculation methods with practical field development data and numerical simulation method， reasonable oil production rate was predicted for the oil field． Based on data of low－permeability fields across the country， the correlation of oil recovery rate， formation flow coefficient and well spacing density was Obtained and oil－recovery rate prediction chart was plotted． With these methods， we compared the reasonable oil recovery rate in Baobei area in Yanqi basin and concluded that， under the current well spacing conditions， the reasonable oil recovery rate ofⅡ formation andⅢ1 subzone in Baobei Block should be 2％ and 2．5％ respectively．
