摘要
在不同的注入水质和大庆油田地层温度变化范围的条件下，应用ＬＳ－３０流变仪及ＲＶ－３旋转粘度计联合测试，对国内外多种类型部分水解聚丙烯酰胺和生物聚合物溶液系统地进行流变性测定和分析研究，深人讨论了增稠特性、零剪切速率特性粘度，确定了聚合物溶液表现粘度随浓度的变化规律及各种聚合物的特性粘度，为矿场聚合物驱工程设计和数值模拟动态预测提供依据。
Abstract Rheologic properties of various partially hydrolyzed polyacrylamide and biopolymersolutions at home and abroad were systematically detected and investigated by means ofthe combination of the LS-30 rheometer and the RV-3 viscometer in different injectionwater quality at reservoir temperature of Daqing Oil Field.The thickening property andintrinsic viscosity at the zero shear rate were discussed in detail and the regularity thatthe apparent viscosity of polymer solutions changes with concentration was determinedwhile the intrinsic viscosity of various polymers was measured,providing the basis ofengineering design and numerical simulation performance forecasting for the polymerflooding in oil field。SUBJECT TERMS:polymer,solution,rheological property,sticky property, shear rate
