摘　　要：由于聚合物水溶液粘度大 ,流动剖面拉长 ,不利于同位素示踪剂载体的均匀扩散。在井底出现絮状物、果冻状松散沉淀物和颗粒状沉淀物分别组成的 3个沉积段。井筒沉积物使电磁流量计的测量值偏高或计数不规则。在测量注聚剖面时 ,宜采用多参数测量 ,运用综合解释技术消除沉积物给注聚剖面测井带来负面的影响。Because of the polymer water-solutions viscosity is much higher and its flow-section is elongated, the equality diffuse of iso topes carrier is interfered There are three sediment-sects at the bottom of a injection-well, they are floccules and jelly-relax sediment and grain-sedime nt in different.Case-sediment makes that the measure value of electromagnetism flowmeter is higher or its take count of is anomaly. More parameter tools sho uld be used when the injection profile of polymer-injection well is measured. F or avoiding the impact of sediment to relative logging technology, integrate-int erpret should be used.
