摘　　要：由于TI 2与TI 3小层吸水差异大,轮南油田TI油组水窜严重,影响驱油效率。针对这一问题,在调驱配方体系室内实验研究的基础上,开展了两个批次9个井组的大剂量整体调驱矿场试验,并对影响调驱效果的诸多因素进行对比分析。结果表明,客观上油层厚度大、物性好、连通性强、非均质性弱、亏空大、剩余油富集的调驱井组调驱后增油降水效果好;主观上注水压力低、注采层位对应关系好、多向或双向受效井多、调驱区块独立封闭的调驱井组调驱后增油降水效果明显,调驱剂与地层孔喉匹配性及其设计用量对调驱效果的影响也非常大。该调驱效果差异性对比分析对今后调驱选井和施工有一定指导意义和参考价值。The reservoir with high temperature and high salinity in Lunnan oil field TI group of Tarim has been found with ineffective water circulation,and serious water channeling because of water absorption differences between TI 2 and TI 3. On the basis of laboratory experiments,two batches of tests including 9 well groups with large dosage overall deep profile control technology had been carried out. The factors affecting the overall displacement effect of Lunnan oilfield has been analyzed. The result shows that,objectively,the effect for well groups with rich remaining oil accumulation,large reservoir cavity loss,large reservoir thickness,good reservoir physical property,strong connectivity and weak heterogeneity is favorable after profile control,and subjectively,the effect for well groups with low injection pressure,good layer corresponding relationship,bidirectional or multidirectional well,independent and isolated block is obvious. The matching degree of particle size of the regulating agent with the pore throat of the formation and its design dosage have strong effect on the profile control performance. This paper provides reference for well selection profile control and construction in the future.
