摘　　要：为抑制和降低黏土矿物水化膨胀和分散转移给油气储层带来的危害,在油田注水开发等过程中需加入黏土稳定剂,因此黏土稳定剂的开发是油田化学品的重要研究领域之一。以防膨率为指标,合成原料采用环氧氯丙烷和二甲胺,通过单因素实验研究乙二胺对2种原料合成有机胺类黏土稳定剂的防膨性能影响,采用正交实验优化合成条件。结果表明:在n(C_(3)H_(5)ClO):n(C_(2)H_(7)N)为1.2:1、反应温度为60℃、反应时间为2h、C_(2)H_(8)N_(2)投加质量分数为2%时,合成的有机胺类黏土稳定剂的防膨率最高,为86%,与油田现场所用的黏土稳定剂COP-2相比具有良好的防膨效果。In order to restrain and reduce the harm of hydration expansion and dispersion transfer of clay minerals to oil and gas reservoirs,clay stabilizers need to be added in the process of oilfield water injection development,so the development of clay stabilizers is one of the important research fields of oilfield chemicals.Using epichlorohydrin and dimethylamine as raw materials,the anti-swelling rate as an index,influence of ethylenediamine on the anti-swelling performance of organoamine clay stabilizer synthesized from the two raw materials was studied by single factor experiment,and the synthesis conditions were optimized by orthogonal experiment.The results showed that when n(C_(3)H_(5)ClO)∶n(C_(2)H_(7)N9)was 1.2∶1,the reaction temperature was 60℃,the reaction time was 2 h,and the mass fraction of C_(2)H_(8)N_(2)was 2%,the anti-swelling rate of the synthesized organoamine clay stabilizer was the highest,being 86%.Compared with the clay stabilizer COP-2 used in oil field,it had good anti-swelling effect.
