摘　　要：低渗油田无因次采液指数和采油指数的变化特征与高渗油田相比有很大差别,因此,高渗油田水淹层的界定标准不能应用于低渗油田,否则,将影响到不同级别水淹层产能预测和合理挖潜措施的制定。为了减少水淹级别与含水开发阶段因划分界限不同而产生相互交错,使不同类型油藏或同一油藏不同储集层之间具有可对比性,提出了按含水开发阶段进行水淹级别划分,并利用相渗曲线建立了水淹级别识别、产能预测和剩余油潜力评价等方法。经丘陵油田实际应用,不同水淹层试油产水率与预测结果一致,可为其他油田提供借鉴。Low permeability oilfield＇s dimensionless fluid productivity and productivity indexes variation characteristics have very big dif-ference compared with high permeability oilfield,so high permeability oilfield water flooded layer＇s defined standards cannot be applied tolow permeability oil field. Otherwise,it will affect the productivity prediction of different levels of water flooded layers and the develop-ment of reasonable measures for tapping potential. In order to reduce the mutual crisscross between water flooded level and water-cut devel-opment stage with different boundaries,and make different types of reservoirs or the same reservoir be comparative between them,this pa-per proposes methods for determination of water flooded level limit in terms of the water-cut development stage,identification of the flood-ed levels,prediction of productivity and evaluation of remaining oil potentials by means of relative permeability curves. The case study in-dicates that by different water flooded layers testing,the water production rate is consistent with the prediction results,being worthy of ref-erence for other oilfields.
