摘　　要：针对油田低效循环的实际,研究了减缓含水上升速度的方法。对于纵向非均质高渗透层形成的低效循环主要通过周期注水来治理,厚油层形成的低效循环主要通过细分注水、组合注水层段、精细油井堵水、调剖来治理,达到提高采出程度,提高油田经济效益的目的。Based on the actual of the low effective circulation in oilfield,it has been researched that the methods for making the water cut rising velocity to slow down.The low effective circulation made by the vertical heterogeneity layer of high permeability can be managed mainly by cyclic waterflooding,the low effective circulation made by the thick oil layer can be managed mainly by subdiviser waterflooding,combining waterflooding,finer water plugging and profile control to enhance the oil recovery and to increase the economic efficiency of the oilfield.
