摘要/Abstract

摘要： 在室内测试了缔合聚合物在淡水和模拟油藏盐水中的剪切恢复特性和抗剪切性。实验结果表明,与部分水解聚丙烯酰胺HPAM相比,不管是在淡水还是在模拟油藏盐水中,疏水缔合水溶性聚合物具有很好的剪切稀释性和抗剪切性,进一步证明了疏水缔合作用对缔合聚合物溶液的抗剪切性的贡献。对油气开采用缔合聚合物的施工设计有一定指导意义。

Abstract: The characteristics of shear recovery and resistance of hydrophobically associated polymer (AP4) in lab fresh water and simulated reservoir brine are tested. The experimental results show that AP4 in both conditions has good behaviors for shear thinning and shear resistance compared with partially hydrolyzed polyacrylamide (HPAM), more indicating that the hydrophobical association effects greatly on shear resistance behavior, and this polymer for oil-gas recovery can be allowed to implementation and application of it for oilgas recovery.

Key words: polymer, shear velocity, quality concentration, shearing degradation
