APJL-3低度交联体系的研究与应用

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。

The Study and Pilot of APJL-3 Low-crosslinked System

AP-hydrophobically associating water-soluble polymer compare with the general HPAM, it has better performance of viscosify-building salt-resisting and temperature-resisting,APJL-3 low-crosslinked,system by using AP-polymer compares with HPAM system,the performance characteristic of salt-resisting,temperature-resisting,shearing-resisting and oil displace-ment efficiency has a obvious improving.Moreover,it had gotten satisfied effect of stimulating by the field testing,showing the better applicating perspective.This paper introduced the APJL-3 low-crosslinked system formulation's optimization,evaluating of the performance characteristic of salt-resisting,temperature-resisting and shearing-resisting,and modelling the effect of profile control and oil displace-ment in lab.
