| 摘 要： | 以丙烯酰胺和丙烯酸为共聚单体,过硫酸铵-亚硫酸氢钠为氧化还原引发体系,Span 60/Tween 80为复合乳化剂,在白油中进行反相乳液聚合,制备出了稳定的“油包水”型乳液,并初步评价了其在不同的钻井液中的性能.结果表明:该乳液在淡水、盐水以及饱和盐水钻井液中随着质量分数的增加具有较明显的增黏性能,但其在高温下的老化性...

| Abstract: | The stable water/oil emulsion was prepared in inverse emulsion polymerization with acrylamide and acrylic acid as comonomers,ammonium persulphate and sodium bisulfite as the redox initiation systems,Span 60 and Tween 80 as the composite emulsifiers,and white oil as the continuous phase.The performance of the inverse emulsions in drilling fluid was evaluated.The results indicate that with the increase of mass fraction,the copolymer emulsion exhibits significant enhanced viscosity in fresh water drilling flui... |
