摘　　要：通过多烯多胺类物质二乙胺、二乙烯三胺、三乙烯四胺、四乙烯五胺分别与盐酸、草酸、乙酸反应合成黏土稳定剂。对合成产物的性能进行评价,结果表明:采用盐酸合成的黏土稳定剂在0.5%(质量分数)投加量、140℃、放置14 d条件下的防膨率达87%以上;耐水冲刷能力顺序为四乙烯五胺盐酸盐>三乙烯二胺盐酸盐>二乙烯三胺盐酸盐>乙二胺盐酸盐。岩心流动实验表明,多烯多胺盐酸盐黏土稳定剂防止黏土颗粒膨胀和运移的综合性能良好,对岩心的伤害率在20%以下。Polyene polyamine salt clay stabilizers are synthesized by polyene polyamines such as ethylenediamine,diethylenetriamine( DETA),triethylenetetramine( TETA),tetraethylenepentamine( TEPA) reacting with hydrochloric acid,oxalic acid,acetic acidt separately,and the performance of the synthesized products is evaluated. The results show that: the anti-swelling ratio of the clay stabilizers synthesized by the reaction of polyene polyamines with hydrochloric acid can reach to above 87% after 14 days at 140 ℃ when their mass fraction is 0. 5%; The order of the water scouring resistance capacity of the polyene polyamine salts is TEPA salt > TETA salt >DETA salt > ethylenediamine salt. The flow experiments of cores show that the polyene polyamine hydrochlorides are of good performance to prevent the migration and swelling of clay particles,and their damage ratio to the permeability of core samples is below 20%.
