注采井间窜流的判别是油田开发和动态管理的重点和难点，杨家坝油田E1f2^3属于裂缝-孔隙砂岩油藏，注采井间窜流明显，但注采井间窜流的方向和严重程度认识不清，致油田开发调整效果不理想。通过研究应用注采井间窜流预警方法，在充分应用动、静态资料的基础上，筛选归纳了16项判别指标，并通过模糊评判方法对杨家坝油田E1f2^3注采井间的窜流方向和严重程度进行实时预警，取得较好效果。

The discrimination of injection - production well fluid channeling is an important and difficult point in oil - field development and dynamic management. The E1f2^3 of Yangjiaba Oilfield belongs to fracture - pore sandstone reservoir, where the interwell fluid channeling is obvious, but the direction and severity is not recognized clearly, so the effect of oil- field development adjustment is poor. On the basis of dynamic and static data, 16 discrimination indexes of well fluid chan- neling were screened and concluded. By the use of fuzzy discrimination method, the real - time early warning for the direction and severity of injection - production well fluid channeling of E1f2^3 inYangjiaba Oilfield was carried out, and good effects were obtained.
