摘　　要：以平平加O-10和对氯甲基苯乙烯为原料,通过醚化反应合成出一种具有疏水效应的大单体,并对产物结构进行红外表征,由羟值测定法计算产率达到90%。采用反相微乳液聚合方法合成疏水缔合水溶性聚合物微球,并对所合成的微球进行性能评价。结果发现:疏水缔合交联聚合物微球溶液具有较好的封堵性,耐盐性和抗剪切性的特点;在岩心驱替试验中,复合体系所提高采收率为20.54%,远远超过单独使用AP-P4溶液的8.2%。A sort of hydrophobic monomer was synthesized through the direct Etherification reaction using peregal O-10 and p-chloromethyl styrene as raw material.The structure of the monomer was characterized by Fourier transform infrared(FT-IR).The yield of raw material was detected by the method of hydroxyl value,and was to the 90 percent.Hydrophobically associating water-soluble polymer microspheres was prepared by inverse microemulsion polymerization.And evaluate the performance of the microspheres.The results showed that the soluble features in sealing ability,salt tolerance and shearing resistance.In the core displacement test,the enhanced the recovery ratio of compound system is 20.54%,more than the 8.2%of the pure AP-P4.
