摘　　要：针对调整井在动态压力作用下,水侵导致的环空窜流问题,以AMPS、AM、MA和St为原料,以自由基胶束聚合法,合成了一种固井水泥浆用水溶性疏水缔合聚合物HAWSP-L,其结构经IR和SEM表征。HAWSP-L的水泥浆性能评价结果表明:HAWSP-L具备良好的抗水侵能力,含HAWSP-L的水泥浆抗窜通压力达到5.3 MPa。In order to solve the problem of annulus channeling caused by water invasion under dynamic pressure in adjustment wells,a water-soluble hydrophobic associating polymer HAWSP-L for cementing slurry was synthesized by using AMPS,AM,MA and St as raw materials.The structure of HAWSP-L was characterized by IR and SEM.The evaluation results of the slurry showed that HAWSP-L has a good anti-water invasion ability.Compared with the 0.1 MPa channeling pressure of water invasion blank slurry,the channeling pressure of HAWSP-L water invasion slurry reached 5.3 MPa.
