    • Disclosed are a flexible polymer, particles made from same, and a process for preparing the particles. This flexible polymer is obtained from copolymerizing monomer (A) and monomer (B), wherein monomer (A) is one or more water-insoluble unsaturated diene monomers; monomer (B) is at least one compound with the general formula of wherein R is C1-C12alkyl, C1-C12 alkyl aryl, C1-C12 alkyl ether or C1-C12alkyl ester. Monomer (A) is in an amount of 60-90% by weight of the total combined weight of monomer (A) and monomer (B). Monomer (B) is in an amount of 10-40% by weight of the total combined weight of monomer (A) and monomer (B). The flexible polymer particles show excellent flexibility, deformability, elasticity as well as stability. They can be used in oilfields in nearby wellbore profile control and in-depth profile control or as in-depth flooding fluid diverting agents. They can also be applied in water shutoff in high temperature and high salinity production wells; preventing chemical channeling in polymer and ASP (alkali-surfactant-polymer) flooding; temporarily plugging in acidization; huff and puff; and preventing in-depth channeling in steam flooding, loss of circulation control and filtration control, and the like.
    • 公开了柔性聚合物,由其制成的颗粒和制备颗粒的方法。 该柔性聚合物由共聚单体(A)和单体(B)得到,其中单体(A)为一种或多种水不溶性不饱和二烯单体; 单体(B)是至少一种具有通式的化合物,其中R是C 1 -C 12烷基,C 1 -C 12烷基芳基,C 1 -C 12烷基醚或C 1 -C 12烷基酯。 单体(A)的单体(A)和单体(B)的总组合重量的60-90重量%。 单体(B)的单体(A)和单体(B)的总组合重量的量为10-40重量%。 柔性聚合物颗粒显示出优异的柔韧性,变形性,弹性以及稳定性。 它们可用于油田附近的井筒剖面控制和深度剖面控制,或用作深度淹没液体转向剂。 也可应用于高温高盐生产井的关闭水中; 防止聚合物和ASP(碱 - 表面活性剂 - 聚合物)淹水中的化学通道; 暂时酸化; 气喘吁吁; 并防止蒸汽溢流的深入沟通,流通控制和过滤控制的损失等。
