合成了一种离子型动力学天然气水合物抑制剂DVA，用四氢呋喃法评价了抑制效果。结果表明，最佳的合成条件：在氮气保护下，N（N-乙烯己内酰胺）：N（丙烯醇）：N（甲基丙烯酸二甲胺乙酯）=3：1：4，反应温度60℃，反应时间8 h，pH≈7，单体浓度50%，引发剂加量为0.6%（占单体总质量百分数）。抑制剂加量为0.2%~0.8%时，水合物的生成温度可以降至-7.0~-8.4℃，加量0.5%时抑制效果最好；0.5%的抑制剂和5%~9%的热力学抑制剂（无机盐或醇）经行复配时，水合物生成温度下降至-9.0~-13.1℃。

Synthesized a ion-kinetic hydrate inhibitor DVA by a series of single factor experiments and valued the properties of this new hydrate inibitor using THF method. The result showed that the optimum reaction conditions are obtained as follows:under the protection of nitrogen,monomer mole ratio of reac-tion materials of N-vinyl caprolactam,allyl alcohol and 2-(dimethylamino)ethyl methacrylate is 3:1:4,re-action temperature of 60 ℃,the reaction time of 8 h,pH≈7,monomer concentration of 50% and initiator amount of 0 . 6%( mass percent of the sum of all the monomers ). This synthesized hydrate inhibitor is more effective than commercial inhibitors. When the dosage of inhibitor is 0. 2% ~0. 8%,the forming temperature of hydrate changes from -7~ -8. 4 ℃. Specifically,the optimal concentration for inhibition is 0 . 5%;When 0 . 5% of inhibitor combine with 5% ~9% of thermodynamic hydrate inhibitors( inorgan-ic salt or alcohol),the forming temperature of hydrate can decrease from -9. 0~ -13. 1 ℃.
