【摘要】 介绍了由淀粉接枝共聚丙烯酰胺/2-丙烯酰胺基-2-甲基丙磺酸(AM/AMPS)制得预交联凝胶调剖剂ROS,评价实验表明,该调剖剂膨胀度在淡水中达250左右,在100 g/L盐水中达70左右,90℃环境中放置8周后性能良好,具有在水中膨胀、在原油中收缩的性能,其柔顺性好,注入性强,调剖效果显著。更多还原

【Abstract】 Precrosslinked profile control agent ROS prepared by graft copolymerizing AM/AMPS with starch was e-valuated. The result showed that the titled profile control agent could swell 250 times in fresh water and 70 times in brine with salt content of 10 000 mg/L. It had good performance after being placed for 8 weeks under 90 ℃. It can swell in water and contract in oil with good flexibility and excellent effects in profile controlling.更多还原
