摘　　要：研制出了一种新型有机无机复合交联剂,该交联剂与主剂HPAM溶液形成一种复合交联聚合物凝胶体系,该体系成胶时间可调,成胶黏度大,抗温可达120℃,抗盐可达250000mg/L,稳定时间长达90d以上;同时,该体系堵水率大于90%,突破压力梯度大于5.0MPa/m,可用于油田开发深部调剖或堵水。A new type of organic and inorganic composite crosslinking agent has been developed in this paper.This crosslinking agent can form a composite crosslinking polymer gel system with the main agent of HPAM solution.Its gel time can be adjusted,the strength of the gel is big,and its temperature resistance and salt resistance are up to 120℃ and250000mg/L respectively.It can be stable for at least 90 d.At the same time the plugging of this gel system is more than90%,the breakthrough pressure gradient is greater than 5.0MPa/m.All of these suggest that the crosslinking agent can be used for field development or water plugging and profile control in deep wells.
