摘　　要：由于海上疏松砂岩油田渗透率高、非均质性严重,近年来产量逐渐递减,含水率逐渐上升,常规的凝胶连续相封堵体系已经无法满足其控水稳油的需求。本文以引进纳微米微球深部调驱技术为目的,选取核壳自胶结微球,微米微球和纳米微球测试其溶胀性、注入性和封堵性,与储层渗透率相匹配,进行平行非均质填砂管驱替实验,实验结果表明聚合物微球具有能量累加能力,提高微观波及体积,起到很好的增油效果。纳微米微球深部调驱技术在渤海油田A井组多次实施后,控水稳油效果显著。Due to the high permeability and serious heterogeneity of offshore loose sandstone oilfields,in recent years,the production has gradually declined and the water content has gradually increased.The conventional gel continuous phase plugging system has been unable to meet its needs for water control and oil stabilization.In this paper,with the purpose of introducing deep profile control and flooding technology of nano and micro spheres,core-shell self-cemented micro spheres,micro spheres and nano spheres are selected to test their swelling,injection and plugging properties,matching the reservoir permeability,and proceeding in parallel.In the heterogeneous sand-packing pipe displacement experiment,the experimental results show that the polymer microspheres have the ability to accumulate energy,increase the microscopic sweeping volume,and have a good oil-increasing effect.After several implementations in well group A in Bohai oilfield,the effect of stabilizing oil and controlling water is remarkable.
