摘要
从大庆油田非均质油层调剖实际需要出发， 通过阴、阳离子聚合物在天然岩心上静、动吸附量， 阻力系数和残余阻力系数等参数的测定， 对阴、阳离子聚合物的吸附能力， 阻力系数和残余阻力系数大小作出了评价。在此基础上， 确定大庆油田阳离子聚合物达到饱和吸附时的最低浓度约为２ ０００ｍｇ／Ｌ， 并在非均质岩心上进行了调剖效果评价， 其实验结果为油田实施阴、阳离子聚合物交替注入调剖技术提供了依据。
This paper measures the parameters of the static and dynamic adsorbance, resistance coefficient and residual resistance coefficient of anionic and cationic polymer on natural core, and evaluates the adsorbing ability, resistance coefficient and residual resistance coefficient of them. Then it determines that the lowest concentration of cationic polymer in Daqing Oil Field is 2 000 mg/L when it is saturated adsorbed, and evaluates the profile control effect. The experiment result provides an evidence for the alternative injection of anionic and cationic polymer in the oil field.
