摘要
牛圈湖油田储层平面、剖面非均质性严重,井间连通性差,分区开发效果差异大。而单井注水吞吐采油方法是利用油层的亲水性,发挥毛管力吸水排油的作用实现水驱,能有效地补充地层能量,恢复地层压力,提高采收率。该方法在牛15-5井实施后,效果十分显著。
Niujuanhu oilfield is characterized by serious reservoir heterogeneity in plane and section, poor interwell communication and great difference of development effects of division. The method of single well cyclic water injection indicates that cyclic water injection can take advantage of the hydrophilic property of oil layer and the water-intake and oil-drainage mechanism of capillary pressure to realize waterflooding, complement formation energy, restore formation pressure and improve oil recovery effectively. The method has an obvious application effects in Well Niu 15-5.
