摘要
根据油田中常用硫酸盐防垢剂的分子结构,设计了一种三元共聚物防垢剂THF。以马来酸酐(MA),丙烯酸(AA)和丙烯酸甲酯(MAC)为单体,双氧水(H2O2)为引发剂,采用自由基水溶液聚合,制得共聚物防垢剂。分析了不同合成条件对防垢性能的影响,评价了防垢剂对硫酸钡的防垢效果。结果表明,作为油田水处理剂,该防垢剂产品对硫酸钡垢有一定的防垢能力。在MA∶AA∶MAC为1∶0.4∶0.6,引发剂双氧水用量为单体的12%,单体浓度为30%,80℃下反应3h所得的共聚物防垢效果较好。防垢剂THF对抗成垢离子溶液温度、pH值、成垢时间的能力较强,并且在成垢离子较多的条件下有较强的阻垢能力。
Kraft used in the oilfield scale of the molecular structure, design of a terpolymer scale THF. Maleic anhydride （MA）, acrylic acid （AA） and methyl acrylate （MAC） for the monomer, hydrogen peroxide （H2O2） to the initiator, in aqueous solution by radical polymerization, a copolymer of scale inhibitor. Synthesis of different conditions on the scale of the impact evaluation of the scale of the scale effect of barium sulfate. The results show that, as oilfield water treatment agent, the scale of barium sulfate products on a certain scale scale capacity. In MA： AA： MAC is 1：0. 4：0. 6, hydrogen peroxide initiator monomer dosage of 12%, monomer concentration of 30%, 80℃ response three hours from the copolymer scale effective. Prevention of THF--scale confrontation ion solution temperature, pH, time-- scale has strong ability, and more ions into dirt under the conditions of a strong ability to scale.
