Experimental study on hot water extraction for oil sands in the Oil Sand Hill of Qinghai oilfield
摘要
Abstract
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.关键词
