摘　　要：异常渗流油藏往往因为或是流体性质异常、或是多孔介质异常、或是流动状况发生变化 ,从而造成流体渗流不符合达西渗流规律。通过室内试验 ,确立了异常渗流油藏油水两相渗流特征的研究方法 ,测试了其油水两相相对渗透率曲线 ,并由无因次采液 (油 )In abnormal percolation reservoirs, often because of abnormal fluid property, or abnormal porous medium or variation taking place in flowing status, fluid percolation without being consistant with the rules of Darcy's flow is caused. Through an experimental test, a method for studying 2 phase percolation property of oil and gas in abnormal percolation reservoirs is established, and the related permeability curves of oil and gas are tested. The variation rules of dimensionless fluid (oil) producing index and calculated predicting curves are used to study the 2 phase percolation properties in the abnormal percolation reservoirs.

关 键 词：异常渗流油藏 渗流特征 相对渗透率 无因次采液(油)指数
