一种油水乳状液的破乳脱水方法
摘要：
本发明涉及一种油水乳状液的破乳脱水方法，包括：将油水乳状液与含盐水和破乳剂混合，进行破乳脱水；含盐水的总离子浓度为10000～300000mg/L，用量为油水乳状液体积的10％～50％；所述的油水乳状液为稠油与水形成的油包水乳状液，其中含有乳化降粘剂。本发明适用于含有稠油和乳化降粘剂的油田采出液的破乳脱水。
摘要（英）：

The invention relates to a demulsifying dehydration method of an oil-water emulsion. The method comprises a step that demulsifying dehydration is carried out through mixing the oil-water emulsion with salt-containing water and a demulsifying agent, wherein the total ion concentration of the salt-containing water is 10000-300000mg/L, and the application amount of the salt-containing water is 10-50% of the volume of the oil-water emulsion; and the oil-water emulsion is a water-in-oil emulsion formed by viscous oil and water, and contains an emulsified viscosity reducer. The method is suitable for the demulsifying dehydration of oilfield produced fluids containing the viscous oil and the emulsified viscosity reducer.
