| 摘 要： | 针对滨南水驱常规稠油油藏综合含水快速上升、低产低效注水开发的特点,选择滨31-11井组开展WD体系驱替技术研究,通过对5种不同驱替浓度的驱油体系效果评价,筛选了适合于该区块的体系。通过WD驱油体系溶解性、配伍性、在岩石矿物上的吸附量以及药剂对脱水的影响等实验,证明该体系能有效降低原油粘度,提高驱油效率,改善水驱开发效果,提高最终采收率。

| Abstract: | Aimed at the properties of fast increase in composite water cut and low level of recovery efficiency during the water-flooding treatment of conventional heavy oil reservoirs in Binnan,Bin 31-11well cluster has been chosen as the experimental plot and a WD system has been experimentally studied in this cluster.Performance evaluation and displacement plan has been studied systematically.Experimental data including the solubility,compatibility,absorbance and the influence of chemicals on the dehydration effect have demonstrated that the WD system can effectively reduce crude oil viscosity,improve oil flooding efficiency,water flooding effectiveness and the recovery ratio of conventional heavy oil.Keywords : water-flooding,conventional heavy oil,WD flooding system |
