离子液体的合成及在稠油改质中的应用研究

摘要

Three types of ionic liquids 1-butyl-3-methylimidazolium chloride[BMIM]Cl 、1-butyl-3-methylimidazolium tetrachloroferrate [BMIM]FeCl4 and hydrochloric triethylamine nickel chloride Et3NHCl-NiCl2 were synthesized,and studied the effect of the three types of ionic liquids to heavy oil in different addition amount.The results show that preparation of transition metal modification [BMIM]FeCl4 can make effective viscosity reduction of heavy oil under the condition of a certain amount,the rate of viscocity reduction was above 34.12 %.This shows that ionic liquid can make the lower viscosity of heavy oil in the mining process,increase the recovery factor and reduce production cost.%合成了[BMIM]Cl、[BMIM]FeCl4和Et3NHCl-NiCl2三种离子液体;并研究了这些离子液体在不同加入量时对新疆哈浅22号稠油的改质效果.结果表明,过渡金属改性制备的[BMIM]FeCl4在一定量的条件下可使稠油有效降黏,降黏率达34.12%以上,这说明离子液体可使稠油在开采过程中降低黏度,提高采收率,降低采油成本.
