摘　　要：针对吴起油田油藏非均质性严重,注水区油井高含水及水淹现象日趋严重,常规的调剖、调驱技术治理效果欠佳的实际,开展了弱凝胶微粒复合调驱剂研究及现场试验。结果表明:(1)调驱设计配方为:高分子缔合聚合物浓度0.1%,黏土浓度2.0%,弱凝胶调驱剂浓度0.5%～1.0%,高分子缔合聚合物浓度0.1%;(2)试验达到了预期效果,10个井组6个月有效期内累计增油1 782t,含水下降24%,注水压力升高1.4MPa,平均吸水强度指数减小1.20m^3/(d·MPa),为油田的增储上产带来较好的经济效益,适用于吴起油田高含水井组治理。Aim at Wuqi oilfield reservoir heterogeneity is serious,water injection zone increasingly serious phenomenon of oil well high water cut and water flooded,the inefficiency of the conventional profile control technology of profile modification and oil displacement control,carried out the weak gel particles compound oil displacement agent research and field test.The results showed that:(1)The design formula for the tamper drive is:Polymer connective polymer concentration 0.1%,clay concentration 2.0%,weak gel driving agent concentration 0.5%~1.0%,polymer connective polymer concentration 0.1%.(2)The experiment achieved the desired effect,ten well group increased 1 782 toil within the validity period of 6 months,a 24% drop in water,the water injection pressure1.4 MPa,an average of 1.20 m^3/(d· MPa),It is suitable for the management of high water-cut well group in Wuqi oilfield.
