秦家屯油田位于松辽盆地南部,梨树断陷东部斜坡区,属于非均质断块层状油藏。经过10余年开发,油藏在不同方向的物性差异、层间矛盾、层内矛盾十分突出,为了解决这些矛盾,有效的改善吸水剖面,使油田稳产,2010年在秦家屯油田进行了分层注水措施,油藏吸水状况良好,水驱控制、动用程度有所提高,有效地改善了剖面的吸水差异,同时使油藏对应油层得到了充分的能量补充,油田采收率有所提高,自然递减同比下降,极大地改善了开发效果,达到了油田稳产的目的,具有重要的意义。

The Qinjiatun Oilfield,a heterogeneity bedded fault block reservior located in the southern eastern slop of Lishu Fault Depression,Songliao Basin.The heterogeneity of physical property,the interzonal contradictory and the intrastratal contradictory of reservoir are very conspicuous,which results in the single-zone breakthrough and tonguing in water injection.The technique of zonal water-injection is applied in order to improve the water-injection profile.The application results show that,the zonal water-injection has the clear improvement of the water-injection profile of reservoir and makes the oil layer of reservoir obtain full energy supplement.The applications of the technique in reservoir receive good results,and greatly improving development effect to reach the purpose of stable production.
