摘要
本文采用西德BASF公司生产的丙烯酸和丙烯酰胺的共聚物乳液BP16,用双聚合物段塞法测定了BP16在多孔介质中的滞留和不可进孔隙体积。在较低的注入速度范围内,研究了聚合物溶液的浓度、注入速度对阻力系数的影响,并采用简单的方法计算了聚合物溶液在多孔介质中的粘度。这个计算方法避免了其它计算方法中由一些难以确定的参数引入的误差,所计算的粘度对矿场方案的设计和实施很有参考价值。
ABSTRACT
This paper presents the results of the experimental study of BP16 solutinos flow through long sandpacks. The study was carried out by using a copolymer
contained acrylic acid and acrylamide which were produced by BASF company as
a emulsion form. The retention and inaccessible pore volume of BP16 solution in
porous media was determined by using two polymer slugs. The resistans factor is studied as a function of polymer concentration and injection rate. The viscosities of polymer solutions in porous media are calculated by a simple method which eliminated some errors caused by some other formulas. The calculated viscosities are of great value to the desifning and implementing of field project.
