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-solutions 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 its 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.
