摘　　要：在油田注采过程中 ,由于注采速度过高导致地层发生微粒运移 ,从而堵塞地层孔隙 ,使油气井产量急剧降低。在岩心速敏实验基础上 ,应用渗流力学和采油工艺等基本原理 ,将室内临界流速研究与油田开发相结合 ,建立了微粒运移堵塞预测数学模型。利用该模型对大庆龙虎泡油田部分油井进行了预测 ,结果表明金 191、金 393井存在一定程度的微粒运移损害。The fine particle migration in formation always occurs because of too high injection?production rate and results in pore plugging and dramatically decreased production in oil?and?gas well during the process of injection and production. On the basis of the test of core rate sensitivity, fine particle migration plugging prediction mathematical model is built using basic principles of percolation mechanics and oil production technique through the combination of laboratory critical rate research and oilfield development. Part of wells is predicted by using this model in Longhupao oilfield of Daqing. The result presents that a certain degree of fine particle migration damage exists in Jin 191 and Jin 393 well. It basically tallies with the field situation.
