项目摘要

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.

拟议的项目重点介绍了加拿大石油行业的一个重要问题：描述了蒸汽辅助的重力排水（SAGD）操作中斜面油的特性，并与油砂行业开发工艺关节以管理SAGD Slop Oil。加拿大拥有世界第三大石油储量，主要是油砂形式。原位的下降措施运营引起了加拿大油砂行业的极大兴趣，这打开了恢复大型储量的潜力，这些储量无法通过传统的采矿方法从经济上获得，并且大大降低了具有挑战性的环境问题，例如大量成熟精细的尾矿的积累。在掉落过程中，通过各种操作产生坡度油，并用大量的细固体和水进行乳化，这不是环保友好且难以管理的。在这项研究中，我们建议表征SAGD斜率油的特性以及斜面油乳液的稳定和不稳定机制，主要是通过研究具有化学添加剂和没有化学添加剂的斜率油乳液的界面特性和相互作用。这项工作将提高对斜率油的物理化学特性的基本理解，以及使用选定的化学添加剂的斜坡油乳液的稳定/不稳定机制，这具有极大的基本和实践意义，并将促进有效的破坏机油乳化的有效方法，可以使机油造成不利的机油和型号的型号，从而消除了机油的回收率。
