摘　　要：评价了一种耐高温水基微球调驱剂性能。实验结果表明:不同浓度耐温水基微球调驱剂注入不同渗透率岩心的阻力系数均小于等于5,注入性好;浓度为4 000 mg/L的耐温水基微球调驱剂在岩心中的有效封堵渗透率范围最大,封堵率最高超过90%;该水基微球调驱剂在150℃下有效封堵时间45 d左右,耐温性良好;该耐温水基微球调驱剂可提高渤海油田非均质储层原油采收率15.41%~17.92%。This article evaluates the performance of a high temperature resistant water based microsphere displacement control agent.The experimental results show that the resistance coefficients of different concentrations of temperature-resistant water-based microsphere displacement control agents injected into rock cores with different permeability are all less than or equal to 5,indicating good injection performance.The temperature resistant water based microsphere displacement control agents with a concentration of 4000 mg/L has the largest effective sealing permeability range in the core,with-a sealing rate of over 90%,and good sealing performance.This temperature resistant water based microsphere displacement control agent can improve the crude oil recovery rate of heterogeneous reservoirs in Bohai Oilfield by 15.41%-17.92%.
