【摘要】 针对目前油田普遍存在调剖剂用量大、不经济等缺点,以丙烯酸和丙烯酰胺为原料,通过加入发泡剂A和抗高温单体B,制备了聚合物颗粒调剖剂。确定了调剖剂最佳配方：过硫酸铵加量0.1%,m(亚硫酸钠)：m(过硫酸铵)=1：2,单体总加量40%,m(AA)：m(AM)=2：1,NaOH加量85%,交联剂N,N-甲叉基双丙烯酰胺加量0.0056%、乙二醇加量0.25%。试验结果表明,矿化度为10×10~4 mg/L时,聚合物调剖剂吸水膨胀倍数仍达100以上,可应用于高矿化度和高硬度油田。更多还原

【Abstract】 A polymer particle profile modification agent was prepared using acrylic acid and acrylamide as materi- als,adding foamer A and high temperature resistant monomer B.The optimum formulation of the profile modification agent was determined as follows:m(sodium sulfite):m(ammonium persulfate)=1:2,the total amount of monomers 40%,m(AA):m(AM)=2:1,the amount of NaOH 85%,the amount of crosslinker 0.0056%,the amount of ethy- lene glycol 0.25%.The results showed that swelling times of the polymer profile modification agent was up to 100 under mineralizing rate 10×10~4mg/L.The agent could be used in oilfields with high mineralizing rate.更多还原
