| 摘 要： | 油水乳化液粘度是油田开发中的重要参数，模拟某油田地层条件，应用流变装置测试高温高压条件下油水乳化液的粘度，结果表明，油水乳状液的转相点在含水率为40％～60％，建立了乳化液粘度预测数学模型，其粘度变化规律符合高斯函数和Lorentzian（劳伦兹）函数，随着气油比的增加，乳化液粘度降低，且与常温常压下不含气的油水乳化液粘度有类似的规律，为油田开发提供理论依据。

| Abstract: | Viscosity of water-oil emulsion is an important parameter for oilfield development, which should be measured in condition of high temperature and high pressure using rheometer, when matching the formation conditions of an oilfield. The study shows that the point of reverse phase of water-oil emulsion occurs at water cut from 40% to 60%, by which the mathematical model for the emulsion viscosity prediction is developed. The viscosity variation is accordant with Gaussian and Lorentzian functions. That is, the viscosity of water-oil emulsion will be decreased with increase of gas-oil ratio, similar to the law of gas-free emulsion viscosity at normal temperature and pressure. These results provide the theoretical bases for oilfield development. |
