摘要

AP 型疏水缔合聚合物与普通部分水解聚两烯酰胺比较,具有更好的增粘和抗温抗盐能力。应用AP 型聚合物研制的APJL - 3 低度交联体系比HPAM 交联体系抗温、抗盐和抗剪切性能明显增强,驱油效率提高,现场试验也获得了理想的增油效果,显示了良好的应用前景。介绍了APJL - 3 低度交联体系配方的优选,评价了体系的抗温、抗盐和抗剪切性能,并在室内模拟了调驱效果。

Abstract

AP2hydrophobically associating water2soluble polymer

compare with the general HPAM , it has better performance

of viscosify2building salt2resisting and temperature2resisting ,

APJL23 low2crosslinked , system by using AP2polymer

compares with HPAM system ,the performance characteristic

of salt2resisting , temperature2resisting , shearing2resisting and

oil displace2ment efficiency has a obvious improving.

Moreover ,it had gotten satisfied effect of stimulating by the

field testing ,showing the better applicating perspective1This

paper introduced the APJL23 low2crosslinked system

formulation’s optimization , evaluating of the performance

characteristic of salt2resisting , temperature2resisting and

shearing2resisting ,and modelling the effect of profile control

and oil displace2ment in lab.
