摘　　要：在一定温度下,丁二烯和苯乙烯中加入引发剂、乳化剂和相对分子量调节剂后,聚合生成丁苯胶乳。应用X射线衍射仪、电位测试仪对生成的丁苯胶乳进行结构性能分析,并对丁苯胶乳水泥浆常规物性、水泥石的强度进行了评价。结果表明:丁苯胶乳水泥浆具有丁苯胶乳加量少、抗高温、低失水、低游离水、直角稠化、过渡时间短、防气窜和良好的流变性等特点。水泥浆性能良好,固井质量优异。Using butadiene and styrene after joined the initiator, emulsifing agent and molecular weight regulator, styrene butadiene latex was prepared by polymerization under certain temperature. The structure performances were analyzed by X-ray diffractometer and potentiometric analyzer. The normal properties of slurry and strength of cement were tested in the laboratory. The results show that the slurry has properties of resisting high temperature, low fluid loss, little free liquid, thickening curve emerged right angle, short transition period, control gas channeling and excellent rheological performance. Good cement slurry performance and excellent well cementation effect are obtained.
