Modeling of Stabilization of Water in Oil Emulsions by Asphaltenes

从常规储油层开采石油正变得越来越困难，非常规石油和 天然气资源(如油砂和重油)正在形成油气工业的未来，同时也带来了 不断更新的挑战。其中最重要的挑战之一是沥青质的沉淀和形成。 稳定的油包水乳状液。石油中的沥青质含量很高，特别是在非常规原油中。 因此，沥青质的沉淀和乳状液的形成是不可避免的。沥青质 颗粒沉积在液滴表面，稳定乳状液，使水和油分离。 非常困难。与斯伦贝谢DBR技术中心(DBR)密切合作，作为先驱 活跃在石油和天然气行业领域的研发中心，依靠工程方法，我们将开发 预测沥青质稳定乳化条件以提高乳化效率的模型 分离过程。

Production of oil from conventional reservoir is becoming progressively difficult and unconventional oil and gas resources (e.g. oil sand and heavy oil) are forming of the future of oil and gas industry, while bringing ever-newer challenges. One of the most important of these challenges is asphaltene precipitation and formation of stable water-in-oil emulsions. There is a high content of asphaltenes in oil, particularly in unconventional hydrocarbons; therefore, the asphaltene precipitation and the emulsion formation are not evitable. Asphaltene particles deposit on the surface of droplets and stabilize the emulsion, making the separation of water and oil very difficult. In a close collaboration with Schlumberger DBR Technology Center (DBR) as a pioneering active R&D center in the field of oil and gas industry, and relying on an engineering approach, we will develop a model to predict the conditions of emulsion stabilization by asphaltenes to increase the efficiency of the separation process.
