摘　　要：以二甲胺、环氧氯丙烷、2-二甲氨基乙醇为原料,合成一种多羟基的单分子三季铵盐MD膜剂分子,研究了其与一种有机聚季铵盐(聚合物型MD膜驱剂)进行复配得到的驱替用的MD膜驱剂的驱油效果。利用该MD膜驱剂可在三元复合驱后进一步提高采收率达4.55%。A molecular deposition filming flooding （MDFF） agent which is polyhydroxy organic triquaternary ammonium salt have been synthesized acting as reacting material with dimethylamine, epicholorohydrin and 2-Dimethylamine Ethanol. The oil displacement efficiency is studied by MDFF agent which include it and organic tri-quaternary ammonium salt（a polymeric MDFF agent）. MDFF agent gives rise to enhancement in oil recovery as follow： 4, 55Y00 after water flood followed by ASP combinational flood.
