摘　　要：海上平台空间及承重能力有限,而疏水缔合聚合物溶解时间长,聚合物分级强制拉伸装置极大的缩短了疏水缔合聚合物的溶解时间,在一定程度上减小了配注系统的占地面积。为进一步优化海上油田聚合物配注系统,减小其占地面积,通过室内实验研究了填料孔隙尺寸、超重力因子、填料组合对聚合物溶解时间的影响规律,确定最佳聚合物溶解工艺条件,设计了超重力速溶装置。研究结果表明:超重力速溶装置能够很好的缩短聚合物溶解时间,在配液温度为45℃,配液质量浓度为5000 mg/L,装置内部填料组合为300μm/100μm、超重力因子为1307时,AP-P4溶液的基本溶解时间由80 min缩短至35 min,缩短了56.25%。The space and load-bearing capacity of offshore platforms are limited,and the dissolution time of hydrophobical⁃ly associating polymers is long.The polymer-graded forced stretching device greatly shortens the dissolution time of those polymers and reduces the footprint of the dispensing system.To further optimize the polymer dispensing system and reduce its footprint,we designed a high-gravity instant dissolving device.Through laboratory experiments,the influence of filler pore sizes,the high-gravity factor,and packing ring combinations on polymer dissolution time was studied,and the optimal polymer dissolution conditions were determined.The research results reveal the high-gravity instant dissolving device can considerably shorten the polymer dissolution time.The basic dissolution time of AP-P4 was cut by 56.25%,from 80 min to 35 min,with the mixing temperature of 45℃,the mixing concentration of 5000 mg/L,the packing ring combination inside the device of 300μm/100μm,and the high-gravity factor of 1307.
