摘　　要：针对青海油砂山所在地水的沸点低、水资源匮乏、油砂为油润性等不利于油砂水洗分离的问题,通过研究影响油砂分离的因素,采用新的水洗试剂配方,对污水进行絮凝处理。现场试验证明,在水洗试剂的质量浓度为1%、水洗温度约为80℃的条件下,油砂油的收率可达到95%以上,且污水可以循环利用。该项研究对油润性油砂的分离和污水处理具有一定的指导意义。Hot water extraction for oil sands in the Oil Sand Hill of Qinghai oilfield has disadvantages due to low water boiling point,lack of water resources and oil-wet property of the oil sands.Factors affecting oil extraction are studied,and a new washing agent formula is used to conduct flocculation treatment.Field test has verified that when the mass concentration of the washing agent is 1% and washing temperature is about 80℃,the oil recovery percent can be over 95% and waste water can be recycled.This study is of certain guiding significance to oil extraction from oil-wet sands and waste water treatment.
