The proposed project focuses on an important issue in Canadian petroleum industry: characterizing the properties of slop oil from the steam-assisted gravity drainage (SAGD) operation and developing a process joint with the oil sands industry to manage SAGD slop oil. Canada has the third largest oil reserves in the world, mainly in the form of oil sands. The in-situ SAGD operation has attracted much interest for Canadian oil sands industry, which opens up the potential to recover large reserves that cannot be accessed economically by traditional mining methods as well as significantly reduces the challenging environmental issues such as the accumulation of large volume of mature fine tailings. In the SAGD process, slop oil is generated through a variety of operations and emulsified with considerable amount of fine solids and water, which is not environmentally friendly and very difficult to manage. In this research, we propose to characterize the properties of SAGD slop oil and as well as the stabilization and destabilization mechanisms of slop oil emulsions, mainly by investigating the interfacial properties and interaction forces of slop oil emulsions with and without chemical additives. This work will improve the fundamental understanding of the physicochemical properties of slop oil and the stabilization/destabilization mechanisms of the slop oil emulsions with selected chemical additives, which is of great fundamental and practical importance and will facilitate the development of an effective approach of breaking the slop oil emulsions, Improved slop oil management can eliminate the environmental hazard and benefit the recovery of valuable oil products for the petroleum industry.

拟议项目的重点是在加拿大石油工业的一个重要问题：从蒸汽辅助重力泄油（SAGD）操作的废油的特性和开发一个工艺联合与油砂行业管理SAGD废油。加拿大拥有世界第三大石油储量，主要是油砂。现场SAGD操作引起了加拿大油砂行业的极大兴趣，这开辟了回收传统采矿方法无法经济获得的大型储量的潜力，并显着减少了具有挑战性的环境问题，如大量成熟细尾矿的积累。在SAGD工艺中，废油通过各种操作产生，并与大量的细固体和水乳化，这是不环保的，并且非常难以管理。在这项研究中，我们提出了表征SAGD污油的性质，以及污油乳状液的稳定和不稳定的机制，主要是通过调查的界面性质和相互作用力的污油乳状液与化学添加剂和没有。本文的研究工作将有助于加深对污油物理化学性质的认识，以及对污油乳状液稳定/失稳机理的认识，具有重要的理论和实际意义，并将有助于开发有效的污油乳状液破乳方法，改善污油管理可以消除环境危害，有利于石油工业回收有价值的石油产品。
