摘　　要：针对油田高温、高盐调驱使用延缓交联剂的需要 ,同时兼顾环境保护 ,采用络合法 ,经过分子设计 ,研制了一种新型有机铝延缓交联剂L - 2 ,并对其性能进行了评价。该产品为无色无味液体 ,延缓时间在 6～ 48h内可调 ,能与聚合物形成体型结构 ,交联强度大 ,在 1 0 0℃、矿化度为 2 5 0g/L的条件下 ,仍然表现出较好的交联效果 ,符合环保要求 ,而且合成工艺简单 ,可操作性强 ,同时在降低产品生产成本 。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 cross linker,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 cross linked 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.
