Abstract: The researches on Kazakhstan oil-wet oil sand were carried out by the solvent extraction method, from which the best solvent was found out. The influences of oil sand particle, the weight ratio of oil sand, the solvent type, and the extraction time of the oil yield were discussed in the experiment. When naphtha was chose as the solvent with the oil sand size blow 40 mesh, the ratio of solvent and oil sand fixed at about 4∶1, and the reaction time about 10 min at room temperate. The recovery yield of oil from oil sand is above 98%. The experiment is instructive to oil-wet oil sand separation.

摘要： 　    利用有机溶剂对哈萨克斯坦的油润性油砂进行抽提实验，选出了适合哈萨克斯坦油砂的有机溶剂。考擦了油砂颗粒、剂砂质量比、抽提时间对油砂油收率的影响。以石脑油为溶剂，当油砂颗粒小于４０目、抽提温度为室温、剂砂质量比为４∶１、抽提时间为１０ｍｉｎ时，油砂油的回收率可达９８％以上。本实验研究对油润性油砂的分离具有一定的指导意义。
