For the sake of the demanding of precrosslinker in some
oilfield with high temperature and higher salt and in a accord with
environmental protection , this article adopting complexometry ,
through molecular design ,developed a kind of new style organic
aluminium delaid cross2linker ,on there of the performance has
been evaluated . This product is achromatism insipidity liquid ,its
slack time can be adjusted in 6～48 hour ,it can form physical
conformation with polymer ,its cross2linked intensity is large. It
can manifest preferable cross linked effect in the condition of 100
degree centigrade and degree of mineralization of 250 g/L. It
conforms environmental requirements ,its synthesization is simple ,
its operability is strong and it has superior applied valuation of
reducing manufacturing cost and improving combination property.
